poovalanche

when the first pangs of a poo brew turn into a full blown shit storm inside of 2 minutes

"Did you see Todd run to the bathroom?"
"Ya man, must have had a poovalanche"

The rockalanche buried three cars on the mountain road.

Poovalanche

A tower of poop in the toilet so dense and high that each flush cycle only removes the top layer (hence "poovalanche".

Even after multiple flushes a truly potent poovalanche will leave behind a sludgy, pugnacious remnant.

Aged cabbage gives me straight poovalanches every time.
