Scatter Splatter

The act of shitting ones self after a series of solid shits, then you accidentally release diarrhea out of your bunghole and it splatters in your underwear.

I had a Scatter Splatter Incident after a long night of partying.

Scatter and splatter

When you ejaculate so hard it hits the ceiling fan so it coats the ceiling and the walls making them look like they just had a fresh coat of paint

sorry about the scatter and splatter mess in your daughter's room Mr/Missis Smith we got a little carried away but hey at least you don't have to repaint her room this weekend
