I don't remember having a rivalry with a particular sorority. I do remember one sister of a sorority hating me because I was friends with her boyfriend. I knew him for three years before they started dating. Anyway, I was friends with more than half of her sisters, and she started talking sh*t about me to her sisters. They thought that she was nuts because they knew me. It made her look really bad. :p

As for the guys, when alcohol and testosterone mix it is a recipe for beer muscles and big fights. I never saw any fights in person, but I remember seeing one guy with a broken nose. Ouch!
