Anyone who sits on their ass all day and plays video games either on the computer or video game system. Usually overweight for they sit on thier continually enlarging ass and eat Doritos and beans while ruining the controller. Also they usually smell because they have no regular shower times, only when they can put the controller down for a few minutes. Often enough they forget the most important places to wash while in the shower for they can only think of video games. They also continually collect every video game they can get their hands on, even if they don't like it just so they can say they have more than you and have played every game. Will also brag about knowing "everything" about every video game. Normally work in a video store/game store so they can get discounts on their addiction. Will not go to college for they only have one talent and wouldn't want to waste money on college that could be for video games.
Possibly also soon to develop the ever popular "Moobs".
Also see: soon to be evicted and living with their Grandmother in her basement because they overdraft too much on video games.
Gamer: I'm sorry baby, I can't pay rent, I overdrafted on my lame ass PS2 games that I don't even play.
Girlfriend: Then I guess you won't get your Xbox 360.
Gamer: I'm leaving you for someone who understands my needs more!!!
