I put "fraternity guys" on this list because there is a common stereotype of fraternity members, but to be honest there is a wide variation, which depends somewhat on the fraternity at the national level, but primarily on the local chapter. When I was an undergrad, we had the stereotypical fraternities, but there were definitely others. And then there was the fraternity that I belonged to, and to be honest we were mostly nerds and/or rejects, but generally good guys.
