Definition: A griefer is someone who is in a game only to disrupt gameplay and annoy other players. Common griefer activities include team killing, corpse camping, obstructing key map points, and spamming chat channels. Extreme forms of griefing are a bannable offense in most online games, but eliminating it completely has proven to be difficult.
Examples:
That orc warrior is a griefer, he's camping my corpse again.
