To play a computer game, especially an Massive Multiplayer Online (MMO), for extreme lengths of time. This may come at the expense of hygiene, social interaction, even nutrition. Popularized by the article "The Surreal World" by Hayes Reed where he described an Ultima Online obsessed friend's apartment as, "A den of cat ass and murdered time."
