I'll school you in this battle of the baddest Bruce,
(Banner wastes no time in establishing the connection of the two, claiming that Jenner needs to be taught a thing or two, seeing as Banner is the smarter of the two, with the main subject taught being how to rap well, and he claims Jenner needs the schooling.)
With your He-Man haircut and your Daisy Dukes.
(Jenner's haircut is fairly similar to He-Man's, a popular animated character of the 1980s who was known for a flamboyant appearance. Daisy Dukes are extremely short and tight-fitting denim shorts typically worn by women. Banner claims that with these two items, he gives the appearance of a woman while actually being a man in this moment of Jenner's life.)
I hear you're good at running; you're just like the Flash,
(The Flash, like Banner, is a comic book superhero. He has the ability to run so fast that he can travel back in time, so Banner compares him to Jenner's figure as an Olympic decathlete.)
Especially in the 100 meter ditch-your-wife dash!
(Typically, Olympic events are titled by their length in track events (i.e. 450 meter dash). Jenner has left three wives so far, so Banner makes the connection that he literally thinks marriage is a sport and is dashing to the end with a divorce.)
I'm an ace in the lab, acid, base and treble,
(Banner claims to be a great scientist, specifically in his field of chemistry. In chemistry, most compounds can be classified as acids or bases on the pH scale. Banner compares basic compounds to the musical terms bass and treble, which refer to a low and high frequency or range, respectively. Using this work around, Banner is saying his skills in chemistry directly apply to rapping.)
So let me break you down on a molecular level:
(Banner says that he will, quite literally, break Jenner down by beating both physically and verbally to his most basic form just as acids and bases break down things at a molecular level with the exchange of hydrogen atoms.)
You turned one gold medal to a lifetime of green!
(Jenner has actually only competed in one Olympic Games in 1976 during the Cold War. This is important because a Russian had won the year prior, and thus Jenner became an American icon. He exploited this to cross-promote himself with many brands–most notably Wheaties. Banner claims that even with the gold medal, Jenner wanted more publicity and money, which is why he did those cross-promotions.)
The most overrated athlete anyone's ever seen!
(Banner simply states that Jenner is overrated because he only competed in one Olympics.)
You need to carry fatherhood across that finish line!
(Jenner had many wives, and with that, many children, most of which he didn't care for. A tradition in the Olympics is carrying a torch across the finish line. Banner says that instead of a torch, Jenner needs to carry, or support, his children until they are mature adults.)
(Argh!) Kept up with the Kardashians, but left some kids behind!
(Keeping Up with the Kardashians is a reality television show that focuses on the lives of the Kardashian family. The series used to showcase Bruce Jenner while he was married to Kris Kardashian. Jenner was married two times before this, leaving the children he had with said spouses without a father. He chose to stay with the Kardashians and focus on their life together, and even had two new children with her. Banner says that Jenner literally kept being with the Kardashian family, whilst neglecting his other children.)
Now, run along; you'll thank me 'cause I'm getting kinda cranky,
(A pun on Jenner's chosen sport, Banner states that he should use his running to escape from the battle, since Banner is getting angry, which is explained in the next line.)
And trust me, you wouldn't like me when I'm angry!
(Banner often says, "You wouldn't like me when I'm angry," to warn people that they shouldn't frustrate him since anger is the key focus of his powers, with being angry signifying the transformation into the Incredible Hulk. Banner also means that Jenner, even though he is a gold medal-winning Olympic athlete, will never be able to compete with his opposite form.)
I think you're in your element when you're behaving badly.
(Jenner thinks Banner is better, or in his element, when he's the Hulk. An element is a term in chemistry used to organize kinds of atoms.)
Honestly, you're kinda boron when you're happy.
(Jenner continues his opinion from the last line, saying Banner isn't a good rapper while in human form. It is also a pun on the chemical element boron, with "boring.")
I'll lap and pass your ass ten different ways!
(Jenner boasts that he is much faster and better at Banner in rapping and athletics. Jenner competed in the decathlon in the Olympic Games, which is an athletic event consisting of ten different track and field events.)
Decathlon athlete, blast through you like some gamma rays!
(While supervising a trial of a gamma bomb, Banner was accidentally struck by the gamma radiation. Banner's rage caused him to turn into the Hulk as a result, so, indirectly, Jenner says he would make him mad, with Banner ending up being angry and transform into the Hulk like how the gamma radiation affected him.)
The truth is, there's no truce between the Bruces!
(Jenner claims that he and Banner are not equals and there won't be any peace between them.)
You're a drifter being useless; I'm a winner, no excuses!
(Banner tends to move around the world as to keep people safe from his alter ego, thus classified as a "drifter", or a person who moves around from place to place. Jenner says that, while Banner goes from place to place not helping the world in any way, he is winning medals and gaining achievements.)
(Uh!) Beautiful women all up on my jock!
(Athletes at high school who are able to get large amount of girls to like them and like to abuse their popularity are called jocks. To be up on one's jock means to impress another person with extreme effort, mostly due to they are sexually attract to that other person. Bruce Jenner boasted how he was jock himself, that he had many ladies fell in love with him, ending up being their wives, even if a lot of them got divorced.)
I got a home gym; check me on the cereal box, doc!
(Wheaties is a brand of cereal well-known for featuring athletes on their cereal boxes. Jenner was featured on the boxes in 1977 and 2012, and even became a spokesperson for the brand. Doc is the short for doctor, which was the title that Banner has. Bruce is also stating that he works out at home by being put running on a cereal box, which is found in most households.)
You big green freak, don't try to flex!
(Jenner calls Hulk a "freak" and telling him not to "flex", the urban slang for showing off. He could also be telling the Hulk not to physically flex, as in showing off muscle, which is one of the Hulk's defining features.)
If it wasn't for your cousin, you'd never have sex!
(Jennifer Walters, also known as She-Hulk, is Bruce Banner's cousin who also has similar superpowers to Banner. It is mentioned in the comics that She-Hulk is the only person that Banner could have sex with due to the fact that both their bodies were filled with gamma radiation. Jennifer needed a blood transfer to survive, Banner was the only one who could give it to her, the blood then changed her DNA making her She-Hulk.)
(Oh!) You're so strong when you get mad!
(Banner's powers rely on his level of anger, with Jenner admitting the fact that the Hulk is stronger than him.)
Too bad you can't go back and protect your mom from your dad!
(Banner came from a broken home with an abusive father who often beat him and his mother, who died due to said abuse. Jenner says that as the Hulk, he could've easily been able to beat his father, but as Bruce Banner, all he could do was watch.)
(While most of the world praised Caitlyn Jenner for coming out, the Hulk says that her being a transgender woman just gives the false sense of pride.)
Just one more thing Bruce do for cash!
(Bruce Jenner made a large amount of money from sports. The Hulk states that Jenner is so greedy that she only became Caitlyn Jenner for fame and more money.)
Best thing you make: Kylie ass!
(Even with all of her accomplishments, including winning a gold medal and becoming an icon in the transgender community, the Hulk states that Kylie Jenner's curves are greater than anything else Jenner did in her career.)
She eighteen? Hulk SMASH!
(The Hulk is known for saying "Hulk Smash!" whenever he's in combat. Capitalizing on the last line, he realizes that Kylie is 18, which is the age of consent for someone to legally have sexual intercourse in the United States, and says that he can have sex with her now, or "Hulk Smash" her, as "smashing" alludes to the act of having sex.)
That's my teenage daughter, man; I have to forbid this!
(As Jenner is Kylie's parent, she does not approve of the Hulk wanting to have sex with her and sees it as her job to prevent him from doing so.)
I'll put a javelin through your jolly green discus!
(Javelin throwing and discus throwing are both track and field events in the Olympics, which Bruce Jenner took part in. Discus is used as a pun on "dick." She refers to Hulk's testicles as "jolly green," in reference to the Jolly Green Giant, mascot of the Green Giant brand of frozen and canned vegetables, who Jenner relates back to the Hulk because of their similar appearance. Jenner says, to prevent the Hulk from having sex with her daughter, she'll stab the Hulk's genitalia with a javelin.)
Kylie not the type of girl I'mma let you smash on!
(Jenner reiterates here that she disapproves of the Hulk wanting to have sex with her daughter, reusing "smash" in allusion to having sex.)
(Hmm.) You'll get the medal without the decathlon!
(Decathlons are Olympic events involving several different kinds of exercise. For her multiple performances in said events, Jenner was awarded a number of medals over time. In this case, Jenner makes a double meaning on medal, saying that Hulk will earn the "medal" without participating in a decathlon - "medal" in this case meaning the homophone "metal," which is used to imply bullets, which Caitlyn than uses against Hulk as she shoots him several times.)
(Argh!) Hulk is Hulk; no identify as man!
(The Hulk has a hatred towards Banner as a more "puny" version of himself, and chooses not to identify himself as a man. This is also responding to Jenner's first line calling him a man.)
Me thinks Cait might understand!
(Just as Hulk identifies as a non-man beast, Jenner identifies as a female despite being born as a male.)
No gender issue; this Jenner issue!
(The Hulk claims that his hatred towards Jenner is not fueled by her gender transition, something that does not bother him, but rather with Jenner herself.)
Just you being you is enough to diss you!
(He then follows up with this by claiming that the way Jenner acts is material enough for Hulk to insult her, considering her long history with taboo cases such as her divorces, parental abandonment, and even vehicular manslaughter case.)
Look, I understand that you hate yourself,
(Banner deals with self-hate, as he dislikes what he has become as the Hulk.)
But you don't need to blame yourself!
(Banner blames himself for the damages that the Hulk causes in his bursts of anger, as he was the reason for his own creation of the Hulk.)
You're a tiger; stop trying to tame yourself!
(Jenner states that Banner should learn to embrace his alter ego to calm down, comparing him to a tiger being tamed.)
You gotta be big enough to contain yourself,
(The word "contain" has two different meanings: one being having control over others, and two being accepting another individuals respectively; in this case it was the Hulk himself.)
And get hit with a little forgiveness!
(Jenner preaches the importance of forgiveness, which she intends to use with the Hulk for any hurtful accusations he used against her.)
Be green; it ain't none of my business,
(Jenner decides not to bug Banner for being himself, a green beast. This is a reference to the Kermit the Frog meme, in which Kermit is seen drinking tea–like Jenner did in the scene–saying, "But that's none of my business," used in comparison as both Kermit and the Hulk are famously green characters. This is also a reference to the song by Kermit, "Bein' Green".)
But if you think you looking good in those torn-ass clothes,
(Jenner insults Hulk's sense of fashion, as he wears the tatters of the clothes he was wearing as Banner that was destroyed in the transformation.)
You're lying, which means you need a new wardrobe!
(Jenner proposes that Hulk knows he has a bad sense of fashion but can't fix it, which means he needs to get a complete change of clothes. This is also a pun on C. S. Lewis' fantasy novel The Lion, the Witch and the Wardrobe. A rendition of this line was used in a rap battle between Bruce Jenner and Caitlyn Jenner (in which NoShame played Caitlyn), said by Rone (who portrayed Bruce).)
(Aw!) The vision of those shorts kinda scarred me.
(Jenner was emotionally scarred by Hulk's bad fashion sense. This could also reference Vision, a Marvel Comics hero who is a part of the Avengers like Hulk.)
What'd you just rage at a Barney-themed party?
(Hulk is commonly depicted wearing purple shorts, and his green skin adds to that to recreate the color scheme of popular children's character Barney the Dinosaur. Jenner implies Banner got angry and transformed while attending a party themed around the aforementioned character, where he would be wearing something of that color scheme.)
That's probably not something you seen as a child!
(Jenner realizes Banner wouldn't have seen Barney the Dinosaur as a kid due to his poor childhood.)
Not one day did you see your daddy smile!
(Jenner emphasizes Banner's childhood problems as a result of bad parenting. Banner's father, Brian Banner, abused Bruce Banner and his mother, which helped give Bruce his mental illness that helped fuel his Hulk condition.)
"Hulk not strong enough to deal with denial!"
(Even if the Hulk is physically powerful and able to cause mass destruction, Jenner still believes that he is weak in his mental aspect, not having the strength to cope with his own denial.)
Laying you down, easy; that's kitchen tile!
(Jenner says that she can lyrically beat Hulk to the floor and lay him down similar to laying down a kitchen tile.)
Examine this under your microscope:
(As a scientist, Banner uses a microscope to examine small things in greater detail. Jenner recommends that Banner uses the microscope of his to examine the following diss in greater detail.)
You got no neck, but you still fucking choked!
(The Hulk's appearance is so buff that his neck is obscured from view, making him seem like he does not have one. Choking is used as a double-meaning here: to choke is obviously to take great difficulty in breathing, usually due to something obstructing the airway, but to "choke" in a metaphorical sense is to mess up. Jenner describes that, though Hulk appears to have no neck, making it impossible for him to choke, he was still capable of "choking" in way of botching his lyrics.)
After battling me, you're gonna always be pissed,
(The Hulk is known for his immense anger, resulting from Banner's transformation being activated by this emotion. Jenner claims that her rapping will make the Hulk permanently angry. This is also a reference to a famous scene in The Avengers where Banner reveals that his key to keeping the Hulk at bay is not to suppress his anger, but to control it, telling fellow Avenger Captain America, "That's my secret, Cap, I'm always angry.")
So the Hulk will stay forever; neither Bruce will exist!
(The Hulk does not revert his original form until he calms down, as Banner's anger is the source of his power. Jenner believes that the Hulk will remain mad perpetually, since he was dissed, and thus he cannot turn back into Bruce Banner. Jenner will stay as her identity as she is proud to be herself. Therefore at the end of the battle, Banner and Jenner will no longer be Bruces again, leaving the former Bruce's replaced by their transformations.)
My transformation is a giant celebration
(Many people praised Jenner for her transition.)
Say hi to Caitlyn, the voice of the next Jenneration
(Jenner reintroduces herself as Caitlyn, representing the next generation (pun on Jenner's name). Many teenagers today have come out as transgender, and in response society has become more open to people being who they are in such a way.)
You're scared of the monster you have trapped inside
(This line appears to be what developed into the sequence beginning with, "Look, I understand that you hate yourself," and ending with, "Be green; it ain't none of my business.")
I changed on purpose like a butterfly of pride
(While Banner tries to control the Hulk and keep him at bay, Jenner transformed intentionally as a caterpillar would to a butterfly.)
You look like a melted action figure of Glenn Close
(Banner calls Jenner grotesque and disfigured, like a plastic action figure that is partially melted, while comparing her to Glenn Close, a woman with a very bold chin and other similar facial features to Jenner.)
Went from cover of Wheaties to ugly bunches of gross
(Banner mentions that Jenner's transition went from a strong, able sportsman with sponsorships, appearing on the Wheaties cereal box to an ugly woman. "Ugly bunches of gross" is a reference to the cereal Honey Bunches of Oats, comparing that to Wheaties.)

call this my victory lap I'm a trans-champion - (A "victory lap" is commonly done in sports as a celebration of winning, in which the winner runs a lap around the field (or in the case of a track sport, the track). Jenner is a champion at the decathlon, and a champion amongst the transgender community.)
your change was accident - (Banner transforms into the Hulk in accidental circumstances.)
Have a Banner - (Likely refers to the LGBT+ flag, or banner. Name pun on Bruce Banner.)
