Poo Volcano

A phenomenon that occurs during the flushing of a powerful (usually public) toilet when a frothy mixture of poo and water is momentarily burped up from the bottom of the toilet bowl before it's all sucked away and replaced by clean water.

Ewwwww.....a poo volcano erupted when I flushed the toilet and it got all over my ass!
