Urban Legends I've heard at the 3 schools I've helped out here in California:
During house tours, if you're taken on a tour of the house in a group of 2-3 girls, it's b/c they like you and want to make it a personal experience & you're almost guaranteed a bid to that house. On the flip side, if you're having a house tour with more than 4 girls (which happens 90% of the time due to numbers), then don't bother returning b/c they're going to cut you.
Rho Chi Urban Legend heard here at UCR which had me laughing my butt off b/c it's the more ridiculous and stupid one I've ever heard in my life:
If your Rho Chi is blonde, she's definitely a member of XXX sorority. No questions about it!
If your Rho Chi is brunette, she's definitely a YYY sorority sister.
