Shartillery 

Explosive diarrhea that is released in a shart in such a way that it sounds like machine gun artillery fire when it plops into the toilet bowl.

shartillary 

Rapid fire pebble dashing on the back of the toilet. Akin to artillery fire but from your ass.

I launched a major shartillary attack on the back of the porcelain just now. Annihilated the back of the pan.
