All Ass, No Class

A phrase used to denote a girl with a large ass, who is either dressed trashy or doing trashy things. Typically used insultingly or condescendingly, though “all ass, no class” is undeniably attention getting.

Bro 1: Damn, look at her ass! You see that thing sticking out?!

Bro 2: Yeah, but look how trashy she dressed. She all ass, no class.

Bro 1: I don’t care about any of that - that ass is calling me!

Or...

Bro 1: Lisa’s too innocent for me. She’s always wearing sweaters when I see her. She just look like she no fun.

Bro 2: Bruh, you ain’t seen her dance though. She may act like a biblical librarian in the day, but all ass, no class on the dance floor at night.
