funster

1) A person who is just out to cause trouble.
2) Term brought into use by the 1993 SNK game "Samurai Shodown," (aka Samurai Spirits) where, right after the 4th round, the final boss, Amakusa, insults certain players calling them "crazy funsters."

Gen-An: "You're funny... lookin', that is."
Amakusa: "Then die, you crazy funster!"
