It's ok on my campus to say things like, "Oh, what frat is that guy in?" or even occasionally things like, "I'm going to XYZ's frat party." (the last one is still an issue... some people don't like "frat party," either) just to make the word shorter. In emails and instant messages frat is used a lot to shorten the word, but it is TOTALLY un-PC to say "frat boy" or "frat house." BIIIIIGGGG no-no on my campus! Even the GDI's and independants will correct unknowing freshman about using the term. They are reminded that that is a term that went out with the 70's and the stereotypes of Hollywood. It's kinda conisidered a four lettered word on my campus. It's nice to think my campus has respect for greek life like that
