You Are Guinness
You know beer well, and you'll only drink the best beers in the world.
Watered down beers disgust you, as do the people who drink them.
When you drink, you tend to become a bit of a know it all - especially about subjects you don't know well.
But your friends tolerate your drunken ways, because you introduce them to the best beers around.
And to me, the funniest thing about it is that I don't even drink much. Like, I dunno, an ale or two a year? But I do admit to drinking my fair share of 40's of OE when I was 15.
