Reverse Musket

A Reverse Musket is the act of removing an object that is stuck by getting another object stuck in the same manner and compacting both objects by force and is typically referred to when unclogging a toilet by re-clogging with a secondary object and plunging vigorously until a fountain of water is formed.

Tom, "Nah... The upstairs neighbors pulled off a Reverse Musket last night."
