Shnitting 

When you sneeze while about to poop, and launch a turd at high speed for any discernible distance.

So my friend was walking her min-pin, and it sqwatted to poop, sneezed, and began shnitting it's turds about a foot behind it, thus scaring the crap out of everyone else.

Shifting logs 

The act where two people go anus to anus and then one of the participants has a bowel movement into the anus of the other participant. The second participant receives the fecal matter anally and then pushes it back into the anus of the original fecal matter owner.

Tim and Johnny have been getting quite messy with their new shifting logs experiment. Looks highly unsanitary but they seem happy.

shitting like a goose 

The state of having extreme diarrhea. The art of peeing out of your asshole.

Boss: "Are you coming into work today, Bud?"
Joey: "I'm not going to make it today, Boss. I got ahold of some bad street tacos last night and I'm shitting like a goose this morning."
