The worst word you can say about a girl you hate. Cunt is totally overruled by this saying. It emphasizes she is not only a slut, but she is also a wanker. Which is just funny to say.
Also, bitchy blondes who think that they're good at track and soccer when they aren't. They also think they're hot shit, but really, they're air-headed nitwits. Cameron Diaz wanna-bes.
Oh, did you see that girl Sara? She's totes a slut-wanker.
