You're doing all you can
To get in them 'ol jeans
Face it your body's fat
Like it was at seventeen
Well baby you can't get down
So, please don't buy a thong
'Cause the way you'd fill it out
Hey, would be totally wrong
I don't see the that girl you used to be
And if you aint noticed
You're busting at the seams
And your one fat mama
Get off of me
And let's turn it up
And put your butt in a sauna
One fat mama
Oh, whatta ya say babe

Well I know sometimes you say
You can't walk very far
You always lose your breathe
Putting groceries in the car
And you worry about the food
'Cause it goes right to your thighs
But everytime we go out
You always supersize
Oh, and believe me yes you do
Baby, all you need
Is jog a mile or two yeah
One fat mama
Get off of me
And let's turn it up
And put your butt in a sauna
One fat mama
Oh, whatta ya say babe
