Rage Quitting
A conditon in which gamers, through steady provoking, simply cannot take being killed (cheaply or otherwise) anymore and leave a online game game mid-match. Mostly occurs in multiplayer first person shooters. I.E Call Of Duty or Halo.

Warning signs preceding this action include
-The throwing of said gamers controller
-Rampant punching of a sofa/love seat
-Yelling at family members/roommates
-Letting loose a stream of expletives and complaining over in-game chat
Joe: Why is Jack leaving every call of duty match he gets into?
