1.
An individual so addicted to a game, (usually Massively Multiplayer Online Role Playing Games (MMORPG's)) that said individual will take a piss in an empty bottle, rather than spending two minutes going to a toilet because he is affraid to get killed in the game.
Bottle pisser: Oh man I got to take a leak, but I'm in this dungeon. What to do?
Sane person: Just go to the toilet man. I'mm sure your character will survive for 2 minutes. It's just a game.
Bottle pisser: Nah I'll just take a wee in your empty beer bottle.
Sane Person: OMG YOU'RE A BOTTLE PISSER!
