which one?!

So each Frat is different in its own way but their are some general categories.

The Tool/ D-bag Frats: These guys are easy to point out. They were cool in high school and wanted to keep that goin for themselves. Mosly muscle heads/ heavy drinkers. You can expect anything from mandatory work out hours to chugging till you pass out. They easily get the most girls and party the hardest and have the best looking brothers.
They include:
PIKE
TEP
Delta Chi
Lambda
Sigma Pi

The Nice Guys: Your average joe smoe's right here. Basically average everything: Looks, grades, parties, you name it. Don't get the most girls but usually always liked by everyone. Some guys can be nerdy, weird, etc. Down for the whole philanthropy thing if your into that. Actually go for the whole Brotherhood part of the Fraternity thing.
They include:
SAE
SigEp
Theta Chi
Chi Phi

The Geeds/ weirdo's: The name kinda sums these guys up. Your general geeds who aren't really frat guys. The weird scrawny kids who stand still at parties. You might see some of them playing that Humans vs zombies b.s. or trying to hard on the philanthropy.
They include:
Sigma Chi
Fiji
ZBT

The others: Basically the guys you never really hear about. Either cause they are new or just have no presence at all. Can be cool/ can be nerdy but their lack of presense makes it hard to judge.
They include:
ATO
AEPi

The guy above basically sums it up!

Like someone above mentioned i would go to freakday. Only you can really decide which fraternity is best for you, just make an effort to meet the brothers and you will know which one is right for you.
