My best drinking story involved me picking a fight at a sport party (on that was being hosted and attended by athletes) with a girl who lived on my floor in our university dorms. I felt like she didn't have a right to be there because she was
1. annoying
2. not an athlete
So anyway I threw my beer in her face, her friend threw her beer in my face, and I threw the rest of my beer in the friends face. I was carried out of the room by a good friend of mine, a hammer thrower, and then I ended up climbing out of the party through the kitchen window (the house was so packed I couldn't get to the door).
The night ended with those girls coming to me in my boyfriends room trying to pick a fight (my roommate ran to the room in her underwear to warn me). Then we made a huge fuss in the halls, yelling (well, I was laughing) at each other... all on a floor that every RA in the 9 story building just happened to be having a meeting on...
So we all got a talking to, and a slap on the wrist.
Of course, I have my barfing stories too, one of which was in Korea and involved some nasty ginsing rot water (no idea what it's called).... oh the horrible times.
