overgaming

The act of playing games too damn much.

Joe hadn't taken a shower for seven days, and his joystick started to smell. Joe was overgaming with a vengeance this past week.

Overgaming lead to Cartman's mom supplying him with a bucket while playing Warcraft.

Bill: "Hey, Joe! Overgaming will put you in debt!"
Joe: "Don't I know it! Looking at my Steam balance makes me want to jump off a skyscraper!"
