Ooh, I have some and I haven't even gone through rush yet. These are just the rumors that I've heard on campus in my year of school, but I'm not going to repeat them or let them influence me come August.
ABC only hangs out with each other and no one else-considering I NEVER saw these girls wearing letters even though they're the largest chapter on campus, it wouldn't surprise me if this one was true. ABC also apparently only gives bids to Southern girls, despite the fact that I've seen ABC letters on cars with Massachusetts, Illinois, and Oregon license plates.
JKL will give anyone a bid and is desperate for more girls-unfortunately, this is the smallest chapter that is constantly COBing, so it might be true, but since I'm not in them I can't comment on that.
XYZ only dates boys from PQR fraternity-no idea since I've only ever met one XYZ.
LMN is full of drunken party girls-this one was actually told to me by a member of LMN, who showed me an album full of unsavory spring break pics posted by one of her sisters on Facebook.
DEF gives you weed brownies during pref-somehow I doubt this one is true...
