When vagina gets fucked so many times that the inner lips begin hanging outside of the vagina itself. Called Roast Beef because the small thin flaps of skin look similar to the shit you see hanging from the bun of a roast beef sammich from Arby's
John: I was gonna fuck this bitch last night, but when she got her pants off, she has the most wicked Roast Beef I've ever seen!
Tom: Fuck man.
Tom: Fuck man.
