"Griefing" refers to deliberately irritating and tormenting other players in an online multiplayer game. Wherever there's a large group of people playing an online game together, there's a smaller group that just wants to make everyone else miserable.
This list has gathered some of the most moments in griefing history from some of the top games on the market as well as some great historical moments. While there are special things that can be done in almost any game, there are a few standard griefing moves in almost every multiplayer game. These consist of exit blocking (when a person stands in the way of the only exit from the spawn room), team killing (dispatching your own teammates) or just plain being annoying over the coms. These irksome players, at times, even resort to crude language and terms to get your goat.
