Nope, I don't think I've ever heard that on my campus. But because I am incredibly awesome, I am allowed to talk to anyone, Greek or not, however I feel like. Just because.
J/k...
Similar: I know there was a girl on my cheerleading squad who was shocked that some guy wouldn't break up with his girlfriend for her...and she's all "But I'm a CHEERLEADER!!" (Uh, and that never made me think of the movie with the same name until right this second. Weiiird.) Anyway, she was totally adorable, but that was just wayyy too funny at the time. Who says that?
