Bootyological

The ranking or placement of girls in the order of the booty sizes.

Guy 1: I'm having a hard time figuring out who I should take to prom. Each of these girls got a fat ass.
Guy 2: Aye man line em up in bootyological order and see who comes out on top.

bootyology

The study of ass; the study of big, big, BIG BOOTY.

"I know a big fine booty 'cause I be a bootyologist, and that means I am an expert in bootyology."
