The act of leaving a cup that is filled with both beer urine on a bar or in an area at a bar where an unsuspecting (and theiving) drunk will assume that the "bait" is an unattended and free beer.
Jim drank half his beer, urinated in the rest, left the land mine on the bar, and waited for someone to take the bait.
