When me and my friends was younger we used to play a game called doorknob. The rules of the game was if you burped or farted your friends would hit you until you touched a doorknob If the person who farted or burped said safety before someone said doorknob then they was safe But if not they had to run to that doorknob while everyone attacked laughter ensued.
When I was less mature, we'd get stoned and goto the store and walk around playing the penis game. Basically shouting penis louder than the person before you. I wonder why we never got thrown out for it...
Honk and point... when you're driving around with a bunch of friends you honk at someone and point... The other day I saw a drug deal in the city and we honked and pointed in the middle of the projects!!!
