Handy Information: How To Chug A Beer

Do your friends make disparaging remarks about your masculinity whenever you fail to chug a beer? Do you feel the need to prove your virility by downing beers faster than any of your buddies? Well read on, and discover secret techniques to humiliate your friends and reclaim your manhood.

The Basics:
Buy some beer. Only do this if you're of legal age (21 in America, 20 in Japan and Iceland, 18 or 19 in Canada depending on province, and around 18-19 most everywhere else... Except France, Netherlands and Denmark, which is 16). Don't bother with good (expensive) beer. If you're drinking it this way, you probably don't care about taste. If you care about taste, this article may not be for you. Read How to Drink Beer.
Practice with water. Your "training" will be more effective if you have your wits about you.
Let the beer warm up a little. It helps if the beer is not ice-cold (talk about brain freeze) but don't drink warm beer, either, or you'll end up with a stomach full of foam.[1]
Let the beer build up bubble if you pour it. Then wait for the bubbles to subside. You want to get rid of as many bubbles as possible because that'll make the beer easier to drink quickly. While you're waiting, the beer will warm up a bit (see previous step).
Right before drinking, hit the bottom of the glass on the table. This releases more carbon dioxide.
Lean your head back slightly. Open your throat, take a half breath right before drinking, and then swing the glass or can quickly so the beer rushes to the back of your throat. Swallow right before the beer actually hits your throat (see video above). Then let gravity take over; the beer should essentially pour down your throat. Try to keep your tongue low and out of the way. Alternatively, you can take a big breath and breathe all your oxygen out of your lungs. Once your throat is clear, tilt back.
Crush the can. If you're chugging from a can, crush it from back to front, as if you're squeezing a tube of toothpaste. This should help you push the beer out of the can and into your mouth faster than it would normally flow. If you squeeze too early or too close to your mouth, you'll trap some beer in the can. Twist the beer can as you crush it.[2]
Slam the empty container down, letting your friends know that you drank a beer faster than they did.
