exploshit

The act of taking a dump so violently, and usually simultaneously with a fart, that the resultant shit spatters onto the destined area, usually a toilet bowl, in the pattern of an explosion.

Jill walks out of the bathroom with a disgusted look on her face.
"What the fuck did you to do that toilet?"
Jack: "I declared biological war and dropped an exploshit into it."
