It's just another quiet day with friends until the music gets pumped up and the beer pumps out. Watch this party animal upchuck his beer while rocking out to Metallica. This guy doesn't know when to stop, but why would you when you are a party animal? It's a "hell yeah" moment for this guy and for the one that filmed it. What kind of beer is he drinking? Who cares, he can't hold it down anyway.
