Griefer

A griefer is someone who seeks to anger and irritate other players. In Guild Wars, a common example of this is someone who quits a PvP or PvE team shortly after joining the game, with no explanation. In PvP, sometimes a griefer will utilize skills to kill him or herself, which can score points for an opposing team in some arenas and may waste a teammate's Resurrection Signet. Other methods of inducing irritation and anger include: scams, harassing other characters (sometimes visually via emotes), and rushing intentionally into unbeatable odds in PvE. Another way is to make a build where the griefer can not be killed, by equipping many healing and defensive skills. This usually makes the griefer sacrifice any offensive skills, creating battles that are extremely long, making the other players quit in frustration. This is common in the Random Arenas
