Sphincter trembles

Fear of relaxing the sphincter after a few days without a poo

Had my morning coffee with my partner this morning and got a case of the sphincter trembles, sat there smiling with fear of how this would play out.

My friend Paul is a sphincter spelunker, thus he is constantly washing feces off his weener.

sphincter-buster

A shit so large, it rips one or more of the circular muscles in the anus on its way out. This usually causes bleeding and mild to intense discomfort.

Male 1 (In the restroom): Call an ambulance!
Male 2: Why?
Male 1: I just had a sphincter-buster! My anus is bleeding and I cant sit down!

Sphincter Farming

When someone farts repeatedly, usually to annoy their coworkers or classmates.

"Oh my God, what is that smell?"
"That new guy in Sales has been sphincter farming all morning."
"Man, he must really hate the boss, huh?"

sphincter fidelity

the ability to differentiate between gas and liquid or solid matter which is causing an urge to be expelled from the anal sphincter.

After you reach the age of 50, you sphincter fidelity goes down and it's wise to go to the restroom to fart.

Jim got so drunk that he lost sphincter fidelity resulting in a nasty shart.
