look up any word, like hipster:

Traditionally, to be eighty-sixed was to be cut off from further booze service. This term comes all the way from the wild west (and not the 1980's as previously defined), where a bartender would only serve the 86 proof whiskey to customers already too drunk (86 proof was reserved for the ladies. The wild west was tough).
Today it means to be cut-off at the bar, kicked out of the bar, or to be cut-off or barred from something in general.
I went to the bar at happy hour and was eighty-sixed by the bartender by 9:00.
