An absolutely stupid game the boys in my class played back in grade 8. The game was simple: snap your wrist in such a way as to quickly smack the genitals of a fellow class-mate and always have your own special area cupped/protected. The point of the game was to have bragging rights at the end of the day, saying you bagged so and so, essentially bagging the most people. Not all the boys wanted to play, but all the boys had to protect themselves. I was one of those boys. One day I got bagged.
