Setup: Hold a beer can sideways, and puncture a hole (you will be drinking from this) in the air pocket towards the bottom of the can with something somewhat sharp (keys or pens are the preferred method).
Gameplay: Open the beer while starting to drink from the hole. This will allow to the beer to flow as quickly as you can drink it. Finish the beer.
