A fecal foreplay game that involves the act of pooping into another persons anus; preferably of a solid nature. The goal is to pass the poo as many times possible without letting it slip out and hit the ground.
I met this girl on craigslist who had a serious poop fetish. We played a few games of Sphincter Shit Swap before getting into grimy, unprotected anal sex. I beat her 12-5.

A particular breed of snake that dwells in the household bath or shower. whilst the bath or shower is in use the snake recoils back into the drain, and if you are unlucky, will spring out of the drain and sink its fangs right in your sphincter.
as a person is going for a shower "watch out for the sphincter snake."
