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!

A particularly large chode, one that poses a health hazard when attempting to backdoor.

OMG Kate tried to do the deed with Travis last night, but it turns out he has a sphincter snapper! She is still in the hospital.
