(v.) The act of an NPC or a spellcaster's pet committing suicide. Often accompanied by the message:
Gebartik slashes Gebartik for 32000 points of damage! Gebartik has been slain by Gebartik! Can be very disconcerting when done by an otherwise normal NPC. e.g. "Yow! That female merchant near the Crossroads just 32K'd herself when I tried to buy something from her!"
