I don't have many off the top of my head (granted there ARE multiple.. my best friend - and sister - jenn and i are terrible about calling pple that we see alot by random/mean/hilarious nick names.. but that aside...
Man, I can't event tell y'all this name cause it's so bad, it's similar to one i was reading on a [much] earlier post here... but she's in a sorority and she got kicked out of at least 2 fraternities on campus for sleeping with too many guys in each. Like she'd walk onto the hall and they'd be like.. we dont want you here, get the hell out of here.. you slut. It's terrible. I think she's outgrown that stage, I know her just through hanging out with a different fraterntiy with whom she hasn't banned herself yet... anyway, she's :
Kappa Kate
-- funny thing, they both start with the same letter, so it just flows. She introduces her self as that name.. like on the phone--> hey it's kate suchandsuch (her last name) and people are like who? and she goes... it's Kappa kate .. and they're like.. OOOOOOOOOOOOOOOOOOH hi.
Everyone has heard of her, but not everyone knows who she looks like. I feel terrible, my friend jenn and i were tailgating and kate walks up and we chatted, then she left, so jenn goes, who's that? i go, kate... she goes,, hmm i dunno her. And I go... uh.. kappa kate, and she's like OOOOOOOOH

that's her?!
Its funny. but terrible too
