I suggest comparing with the original since the lyrics mirrors it.

Lyrics:
Anus... Feces...

Ay Pepto Bismol Boy
Cramped Muscle Oy

Ya got to know I'm a gastroriffic guy
Ma tummy hate OJs like a Tropicana
You got yo know it's acidic in here
Cramped muscle, maybe got the gas in here
I gotta go I ate hot pockets from last tuesday
Donut smothered super tacos nacho cheese with Lima beans
Donut souffle lettuce licorice linguine
Donut be wit pure honey served to everybody
And we're eatin spicy chili throwing up like zombies
Alien trip, crapping out like a rocket
Ain't my --- poopy long
Anus --- still poopin on

CHORUS:
Anus going wrong, anus got it on, anus sore all day, anus poopy long
Anus poopin real, anus cop a feel, anus what a thrill, anus feelin ill

(yeah I'm bored yay yay yay)
Yay, Bung hole, do I speak into this mic? Ok

My rim's so slick I'm such a slip slop anus
Shoppin some new trunks my old one's full of dodocaca
Poo on the go yeah mobile pooper anus
Jet black poop check my style bitch K9

Seasick dung, all day empty my feces panda
Hey I'm on my throne you don't hear me drip anus?
Thick roll feces, anus getting cautious
Be squeezin out poopies, I'm down with the soreness

Anus keep it real sliding down easy
Quite dirty fecal breakin some wind still
Anus crappin foam
Anus flowin long
Anus --- got it going on
Bung hole!

CHORUS

(huh huh It's the king baby, my anus, my anus, my anus)
Souths whorin fecal ables
Anus fresh as my own pee
#2 with indigestion
Anus felching suckin me

Anus crappin out some taters tryna reverse sodomy
Out is only way to go I'll soon be empty hollow me
On a ski anus in pain I'm pooping at minus 43
Anus go go slip n slide boy make a poopy potpourri

Empty my colon feces then we make up and drink some tea
Underwear is stained with pee, ay need a proof just sniff and see

Nincompoopity uncertain though my poop's held back a week
Out it leak so magnifique (Do I smell bacon?) What'd I eat?
You dare me to, Darren, so I show you my derriere
Since I see you scootin over and you even shed a tear

Anus too superior rankin hereby: king of the rear
Poop so well done sniff it so smelly guarantee something to fear

Rep-poo-ken unko top tier
On and on gush out my rear
No paper towel up in here
But ain't my anus such a dear? Ayy~

CHORUS
