Portering

A verb (pronounced "Porter-ing") that describes when a person plays a multi-player video game (such as Halo or Smash Bros.) and sits on the sidelines while the other players fight and kill each other. When only 2 out of all the players fighting are left, the one who took this action tends to win because he did not do anything and angers the other players.

"Freakin' Mike won againg because he was portering the whole time!"
