1) Anyone who thinking drinking is "cool" is dumb anyway.
2) Drinking doesn't kill you. Stupidity and/or alcoholism kills you.
3) Not all alcohol tastes bad, and some people think the stuff you think is gross tastes good.
4) Everything kills you. May as well [responsibly] enjoy yourself if you so choose.

I'm seeing too many extreme attitudes in this thread. Mostly that "omg drinking is poison and uncool." Chill.
