Potato Masher

The act of hiding the evidence that you pooped in a sink or bathtub by smashing your stool with your foot or hand until it has become mashed enough to flow smoothly down the drain. Covering up any evidence that you defiled a bathroom.

I live in a one bathroom apartment but my roommate was using it at the time, so I had to think quick without destroying my pants. So I squatted over the kitchen sink and then proceeded to be a potato masher before my roommate was done in the bathroom.
