Typically referring to an ex-girlfriend or ex-wife (and her lady parts), now also refers to an ex-boyfriend or ex-husband who was an XBox addict.
I'm so glad ExBox moved out. Now I don't have to hear his gaming noise anymore. No shouting at other players who camped him, no more pounding on the desk that's breaking because of his XBox rage problem, and no more zombie or warfare noises coming from the next room giving me nightmares. Now he is free to start his dream of becoming a professional poker player based on his vast success playing with fake money against soccer moms. B'Bye ExBox!!! Hello Peace!
