Teaming

Teaming is a tactic used in multiplayer online shooters (or any game with two teams for that matter) in which one player from one team and one player from the other team cooperate illegally. Most teamers are "trolls" or people with no consideration for the people who actually want to play the game. Usually, the reason teaming is used is so they can kill players from both teams, even with Friendly Fire off. This tactic is dishonest and will usually result in both teamers getting banned.
