Whats a prep? (Sorry, UK DJ).
Anyway, i pretty much hang out with everyone at college. Everyone knows me, i tend to float between the different "groups" of people during each day talking to everyone.
We dont have jocks/cheerleaders etc. here, just the Rock group, the Hip Hop people, the Geeks and the Anti-Social Crew (people who hide out some place and hardly talk to anyone, funnily enough i talk to them sometimes, though i dont hang with them). In fact we got a mix of all kinds of people where i live, there are usually a few disputes about music etc. but everyone pretty much gets along with each other.
