(Name) the quack (my chiropractor)
Was a squat little ape
With a mouse's voice
And a pigeon's gait

2. Cluck, cluck, I don't give a fuck!

Quack

When a girl bends over as if she was bound to get her ass clapped. For a girl with a great, thicc, even juicy ass, you can you use adjectives "mega quack" or even "whole duck pond". Or you can even use adjectives like "chubby quack" for a girl who's overweight and bends over

"Bro where's the quack"
"Homie CeCe bent over"
Or
*thiccum bends over*
"DAMN THATS THE WHOLE DAMN DUCK POND"
