phantom pisser

Not to be confused with phantom shitter, (someone who takes a large shit in a stall toilet and leaves it there for the next person to stumble upon) the phantom pisser involves an individual with a full bladder walking into a public bathroom, switching off the lights, storming the first stall with a person in it by kicking down the door, and then unloading a warm spray of urine on the unlucky stall-goer. The pisser then sprints out of the restroom as fast as humanly possible without revealing their identity, thus becoming the phantom pisser.
