My chapter did nick names for our "families." For instance, my family is called the "Peeps" family (named for those sweet Easter candies and the way an alum laughed--she made a "peep" noise). We even took it a step further and did individual names, which I prefer not to mention. Haha. At one point, all of the sisters even wrote cheers for each other that described us--some were really good, but some were pretty embarassing and I wouldn't want people other than my good friends to hear mine. EVER.
