The fastest way to
chug a
beer is with a
bendy straw.
Place the straw in the neck of the beer
bottle and bend the tip around so that it points at the base. This way when you drink
air will flow in the straw and allow the beer to flow out uninterrupted.
If you can conceal the straw you are that much more impressive to your spectators.
"But achan, what about cans?"
You don't really drink beer in cans do you?
