Shotgun Drinking Game
This is not really a drinking game, but more or less a contest to see who could drink a can of beer the fastest. Very high buzz factor. Supplies: beer, and something to puncture the can with.
Punch a hole near the bottom of the can, on the side. BE CAREFUL: that can is now dangerous with sharp edges possibly exposed. Put your mouth over the hole, lift your head up with the can while opening the can. Drink fast. The first person to finish is the "winner."
