Used in military context: to kill someone. A grave is 8'x6'x3'.... hence 8x6 or eighty six. Our only way out of this one is to 86 the guard and bounce with all his shit. by Anonymous November 06, 2002
In 2002, it was being used in the urban dictionary as to kill someone.
I've always understood "86 someone" to be gangland slang for killing them. I vaguely suspect a nautical origin. But Urban Dictionary gives a different slant, somewhere between your understanding and mine. – Hot Licks CommentedJun 24, 2018 at 22:29
