gack or gakk
verbiage/slang term among LARPers (generally those of the Camarilla
variety) for having a character killed; generally in a
severely brutal manner.
"You hear about that Tremere Archon? He gakked that Birmingham
rogue last week and mailed his remains to the dude's sire."
Not necessarily certain of the genesis of the word, but I'd wager it has
its origins in onomatopoeia: sounds vaguely akin to a death rattle.
