verb. (as popularized by Dane Cook)

A slang term for a female cockblocker. A person who will try and keep you from getting what she will never have herself. Generally a freakishly unattractive, large, hairy woman, who likes to hang out with younger hotter chicks in order to try and hit on the guys that like them. However, once she notices that the guy is not into her, but into her younger hotter associate, she will do everything in her power to sabotage the relationship. Typically she will also try to get with the guy to no avail.
Girl 1: I thought that guy was really into me but all of a sudden he turned cold and his attitude changed.

Girl 2: Wow, was there anyone else involved?

Girl 1: No just Cristina from work who always hangs around. She's fugly though.

Girl 2: Dude, sounds like she pulled a twat swatter on you. I'd kick her fugly ass.
