A large ass, badonkadonk of mythic proportions, much junk in the trunk, etc.
"Damn, Wayne, that girl has a big booty."
"Fuck, Johnson, how many times do I have to tell you not to use stupid, childish slang? The term is 'fine ass'!"
When your booty is so "on point", that it makes people stare even when they don't want to even though, in most cases they do. Squats can result in the booty game being too strong.
Chick 1: damn, my booty looking hella good tonight.
Chick 2: hell yeah, your booty game too strong babygirl! Work it ;)
Chick 1:Alright, thanks b*tch but this booty looking so good I might be able to pull you tonight and I don't roll that way so chill.
