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.

sphincter spelunker

One who makes a hobby of exploring and studying the cave that is surrounded by the annular muscle (i.e., the ass)and able to contract or close a bodily opening. A poostabber. A male homosexual/anal invader.

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 Gravy

Simple diarrhea, preferably brown in color. Should not be the consistency of water. More like the gravy served at Thanksgiving which consists of plenty of white flour.

After eating at KFC two days in a row the greasy chicken produced a light brown flow of sphincter gravy.

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.
