Loaded Cannon 

The act of forcefully passing a kidney stone by ejaculating.

There was no other option but to blow out the stone like a loaded cannon.

Loaded Cannon 

When a person doesn’t shit for a day or two and have to go badly and begin to explode shit all over a unexpecting person who can be asleep.

Dude I wanna do a loaded cannon on Jim tonight
