a pile of shit
Kirby worked up an appetite at the gym so he when he finished he slammed down a shitstack, even eating the curnels of corn. yummmmmm...
2.
When many males all stack up on the shitter, each sitting on the lap of the person below them. They spread their legs and the shit falls down into the toilet.
