Have you guys ever had Day-glos? They're done at my school and are a lot of fun. They're usually held at fraternity houses, and everyone wears white clothes (things you can throw away, like undershirts and boxers) and the walls are covered with black trash bags. You slip and slide around all over the place as you throw paint and soap all over each other. It's messy and a little dangerous (the next day we all had bad bruises and a few cuts) but everyone lets loose and has a great time...
