sphincter mummy 

Residual, rolled up pieces of toilet paper left after wiping one's rectum. These artifacts are often found tangled in the hair adjacent to the sphincter. However, they my become dislodged resulting in the universally hated foot mummy and/or shower drain mummy.

"I was changing my underwear and a sphincter mummy fell out. Howard Carter would be proud."

Sphincter of Death

A co-worker whose shit and farts are so bad that they linger in the office bathroom and waft from his cubicle from morning to closing time, every day. They are so horrid that the rest of his co-workers flee for fresh air every time he lifts his ass and smiles with pride.

Holy Shit! He unleashed his Sphincter of Death again so run for your lives!!!!!!!!!!

sphincter sauce

The juice that discharges from the sphincter muscle in the anal cavity, usually in a swampass condition.

On a hot day, I could feel the sphincter sauce flowing in my shorts.

Sphincter Spigot 

A homemade enema (usually made from a combination of a crack pipe and large funnel) that makes the flowing waters of shit turns into an unsightly sea foam green, resembling the rivers of Ganges.

Man, I got so constipated from all that Heroin, I had to make a sphincter spigot in order to clean out the ol' pipes.

That sphincter spigot really helped me with my cleanse diet.

sphincter clencher 

It means when something is a tense moment, your ass tightens up. So a 'close call' is called 'puckering your asshole'

"This project is really a sphincter clencher. I don't know if we're going to make it on time."
