Commonly referred to as a JWM, it involves unleashing a dump in a public bathroom so damaging that were a janitor to attempt to clean it, it would make a widow of his wife, and an orphan of his children.

A variation is the UJWM, which involves a urinal. This is a high-risk move, but a janitorial fatality is pretty much assured if successful.
Laughing, Ken passed the janitor on his way out of the bathroom, knowing his janitor widow maker was about to strike.
