Crappy Sack is a game identical to hacky sack except you can play with any sort of object EXCEPT a traditional ball or hacky sack. The most common objects used are empty beer cans or keg cups. Other objects can include, but are not limited to: crumpled up paper, wallets, bottle caps, and cell phones.
If you are playing with several people at once and the crappy sack makes it around to each person without hitting the ground, a Crap is achieved and everyone rejoices. Not an easy feat when plastered.
Person 1: You guys want to get a round of crappy sack in?
Person 2: What the fuck are you talking about??
