Teaming

players in a video game who will go work with the opposing side and ruin a game for others to troll, and to get a reaction. It's mostly done in online multi-player games like Friday the 13th, DBD, and any other team-based games.

Counselor player in f13th: Hey Jason, since I'm bored escaping from you/ killing you; let's start teaming up and get the other players killed for a laugh.

Jason player: Alright, I'll kill the others and let you live.

*proceeds to kill other players, lets the teamer survive the night, repair objectives, etc*
*other counselor players get mad at them and send hate messages*
In non-survival horror games:
the player gets annoyed at the other player cheating; *Hey, Opossing team, I know it's against the rules, but, is there any chance you can help me get this cheater eliminated so it will make them quit the game?"
