The act of two people shitting in the same toilet without flushing. (intended as an insult to the bathroom owner)

A shit large enough for two.
I just pooped a shitstack so high, it's coming out of the bowl.

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...
