brontosaurus brawler 

a short or avg. height girl who is extremely aggressive and in most cases quite athletic and strong. always a bitch and sometimes a butch.
an aggressive girl who is flimsy won't do, she has to be physically thick like a tree trunk in that she will always bark a tough game and in many cases bite a vicious game as well.

Bruce Lee: aiyo homey, why didnt you stand up to that bitch?
Jose Contreras: u must be jonin! she's a fuckin' brontosaurus brawler, she could take on the Bears O-line for chrissake.
