Speed Beer is a relatively new drinking made up by Jeph Jaques for his comic "Questionable Content".
It involves sledding and a hell of a lot of beer.

You Will Need:

-A big snowy hill
-Cookie Pans/ Cafeteria Trays/ Sleds
-A lot of beer (A keg will do nicely)
-A designated person to make sure you don't get hypothermia from passing out in the snow
-Plastic Cups

The rules are fairly simple:

-Take your beer, and sleds (Cookie pans and cafeteria trays are preferred)to the top a snowy hill.
-Fill your cup
-Now sled while holding your cup!
-When you reach the bottom, drink whatever is left in your cup
-Repeat this process in turns

Build a ramp, for hilarity will surely ensue.
