I attended classes at two different college campuses, and worked at another. In my experience, every frat/sorority has its own stereotype, and that stereotype generally holds true no matter which campus you're on.
As an example, UT took a serious PR beating over the whole "butt-chugging" incident. But as far as I'm concerned, that wasn't a UT thing, that was a Pike thing. Walk into any Pike house on any campus in America on a Saturday night, and you're likely to see idiotic shizzle like that going down. UT's chapter was just stupid enough to get caught.
(And if there are any current/former Pikes on the board who would like to argue the point, I'd be happy to hear it.)
