ninja kill

Part of a stealth game where a group of individuals dress up as ninjas and must "kill" as many people as they can in one night-(i.e. midnight to sun rise). A "kill" is any stealthily executed pretend slicing of the neck or stabbing of a vital organ usually with a permanent marker of your favorite color to basically "claim" that kill. After marking and claiming his victim the ninja will whisper into the victims ear "NINJA KILL". This will cause any multiply tagged victim to despise the mere spelling of these words, which in turn causes the ninja extreme satisfaction especially after realizing just how many times you marked up this kids neck last night. {extremely fun in a dorm room, fraternity house, or if you've got the ninja balls a sorority house}{drunken, or stoned victims who won't know what to do or for that matter remember are highly recomended targets.}

Holy crap zach got ninja killed eight times last night by red and six by black, that means another ninja kill for fire ninja.
