A way for retards with no life outside of drinking to circle-jerk over how fast they can murder their own livers. See, it works like this; first, you make a plan to go out and drink. Then, you drink BEFORE you go out to drink, so you have an excuse to act like a stupid fuck before you've even had a beer.
Hey, guys, have you heard of this pre-gaming thing? I do it all the time. I drink before I drink so I'm prepared to drink; THAT'S how much I drink!
