haha, i've never been to a lan party, and don't really care too, but this list was damn funny.
This was the best one..
The Finally Got A Girlfriend: Brings his girlfriend to the LAN party. Doesn't have a computer for her, he just wants her around so the other geeks will presumably hail him as a god/look upon him jealously. Unfortunately the rest of the geeks see through the charade and mock him behind his back. Characteristics: 90% of this persons deaths are due to being distracted by her whining about leaving. Will probably show up to next LAN party single again.
