An annoying collection of insecure guys who need help getting laid. No one outside of a frat cares about them, everyone in a frat thinks it is the coolest most badass thing imaginable and use the excuse that it is a "brotherhood" to pass off getting drunk and being idiots. No frat is a "brotherhood" it's a lame excuse to be a part of something for those too insecure to actually make friends. And who think that because they drink on nights they have classes is some how badass. Instead they fail to see the stupidity in just about everything they do. They "rush" and get hazed but no one will say what happens because no one wants anyone else to find out just how pathetic they really are for doing all of this retarded shit just to be accepted. Often these once individuals (now copies) come home on breaks and think they are the shit but get a major reality check from their friends who don't care what they do at their frat house, and get pissed off when some one makes fun of them because of some misplaced sense of pride from being in a frat. Nothing is more pathetic that a frat guy by himself, because alone he is just a prep douchebag, but with his "brothers" he's the balls.

Non frat guy: what'd you do?
Frat Guy 1: i can't talk about it to people not in my frat
