Not really a party story per se but...
My friends and I went to the Viper Room in Hollywood one time (place sucks btw) just to see what it was like and some really drunk mofo hit me square in the face outside while I was smoking with my friends. I swear I didn't do a damn thing to the guy...I dunno, maybe his woman thought I was hot or something. Anyway, so about three seconds after the guy hits me, I'm on my back [in the guy just dropped to him me] with this dude mauling me. Fortunately, I was pretty much dressed in clothes (kinda 70's funk style ala Tyler Durden) I picked up from a thrift store. I'm a pretty athletic, strong guy and I was basically on my first drink so I was able to get the guy off me pretty fast. I got like two good shots in on him before other people broke us up. However, I clearly took the lions share of the damage...I was really upset because I pretty much got my ass kicked and was not given an oppurtunity to kick ass back...the dude was pounding on me for a good 15-20 seconds and then when I get up and start clockin' him a few times, people [his friends I think] restrain both of us.
So I not only got my butt handed to me, I stank like cheap beer...
The crazy thing was, in college I was a fight magnet. Just about half the parties I went to, some guy I didn't know would start a fight with me. Eventually, I stopped going to parties altogether due to the fights and tougher classes.
