Not rap but a song I wrote for a story, as sung by an all-fat, all-girl punk band:
"Hideaway Hefty"
You tell me that I’m beautiful, you tell me that I’m hot
You do me in your living room with everything you’ve got
We order in a pizza and I eat the whole pie
But when you keep me hidden, boy, you know I wanna die
You call me over baby for a Netflix and chill
But all I’m thinkin’ is I think I think I’ve had my fill
I wanna drink, I wanna dance, I wanna paint the town red
But you wanna stay home ’cause you won’t be caught dead
WITH A FAT GIRL!
I’m your hideaway hefty, you’re a closet FA
You don’t even care that your friends think you’re gay
What’s the big deal, dude? I really wanna know
Ashamed to be with me
BUT YOUR DICK DON’T THINK SO!
Let’s go see that band you like, let me meet your bros
Take me to a restaurant or else I’m gonna blow
Not another night inside, dude I think I’m done
I’ll find myself a real man and we’ll go have some fun
Lose my number lover ’cause you know I gotta ghost
Gonna call it over, this relationship is toast
Yeah you love to feed me but my heart is underfed
Jerk off to your phone if you won’t be caught dead…
But you wanna stay home ’cause you won’t be caught dead
WITH A FAT GIRL!
I’m your hideaway hefty, you’re a closet FA
I won’t stay a secret, boy, not another day
What’s the big deal, dude, I really wanna know
You’re ashamed of me
BUT YOUR DICK DON’T THINK SO!
