Bart's version lyrics

Because this song's all about being big, suck a (censored) thin people
If you are super thin super thin you're evil
This catchy tune's message should have been we're equal
But it shames thin women, thin women
Yeah it's kind of clear I like to eat food
But I can write big hit songs and I can sing em too
I see these skinny girls that get super famous
So I say hey why not Meghan Trainor?
I talk like I am black even though I am white
I lived in the suburbs I've had a perfect life
Still there's one thing bugs me I don't know why
But when I see good-looking skinny people I think they should die
Yeah, my mama she told me don't worry about your size
But when I see thin women I want to gouge out their eyes
Gouge out their eyeballs
Gouge out their eyeballs
When I hear Gwyneth Paltrow say oh my god I feel so fat
I want to beat in her pretty face with a baseball bat
Woah!
Now all five of us will do this dumb dance this dumb dance
We're dancing.
These girls need haircuts bad really bad
We can't see
Meghan give me a chance just one chance to rest please
I hired you to dance (censored) it dance!
I'm bringing booty back
Booty never left that statement is trash!
Wow, I'm just playing, don't hate me cause I'm fat!
You're actually normal
Every inch of you is perfect, stop acting like a victim!
Yeah my mama she told me that being big is sexy
And that it turns on men which totally validates me
Makes me feel pretty, makes me feel pretty
I thought this song was supposed to be bout loving you for you
It is
Then why are you basing you self worth off of pleasing dudes?
Now let me reiterate it again if you're thin you're a (censored)
That's totally not true and completely mindless
I'm actually on my way to help the homeless
Nice try but that can't be you're skinny
Meghan your single “All About That Bass” is a hit!
It's platinum!
It's time to lose some weight for your next pop anthem.
But I'm about that bass and that means I'm curvy
That's why everyone like bout this song.
Now Meghan do you wanna be a star or a one-hit wonder?
If you don't lose some weight that would be a blunder
To help you get in shape we've brought in a trainer
It's time to get you ripped! Let's do this!

Key of Awesome's (formely Barely Political) version:

Because you know I got a sinus ache,
in my face, nose trouble,
don't wanna go to space, go to space,
no hubble,
I like a shaven face, shave that face,
no stubble,
just sayin' random things, from my brain.

Yeah it's pretty clear, that I got writer's block,
it's drivin' me insane, feel like a cuckoo clock,
I'm fishing for a hook, just something basic,
what should I sing on top of this bass riff?

I need a goofy phrase, that I can base this on,
that will appeal to kids, as well as soccer moms,
I said I could write singles, they called my bluff,
now excuse me for a jiffy while I make some pop hits up.

'Cause my bang bang boom clap
anaconda's gotta stay high,
'cause your trumpets were rude
chandeliers, happy, Maroon 5,
(I think I like, but that's not quite it)
there aren't enough songs out right now
'bout big behinds (true dat dat),
gonna cover my basses and 
make up one about mine (yeah you should do dat).

Because you know I ain't no skinny waif, I'm not shaped,
like Urkel,
I got handles for love, like a Dove
commercial,
I got a plus-sized butt, that's what's up,
dos bubbles,
I got a sexy shape, like a bass, wait!

You know I'm all about that bass, 'bout that bass,
no treble,
just don't end up obese, that creates,
heart trouble,
but have a piece of cake, that's okay,
don't shovel,
and that was how I made, 'bout that bass
