Sphinctest 

When an anus is nearing a prolapsed state.

I reached my sphinctest yesterday before plopping the mightiest log in my life.

Sphincter Sinatra 

one that loves to break wind and will do so anytime or anywhere (like a crooner that breaks into song in an old 40’s musical)

“Dude, plug that blow hole. Nobody wants to wants to hear your ‘Summer Wind’. Don’t be a sphincter Sinatra.”

sphincter dust 

Crusty and dried on shit on your butt cheeks resulting from shitting in the middle of the night, and passing out on the toilet before being able to wipe your ass.

I passed out on the toilet last night and woke up with my ass cheeks covered in sphincter dust.

I need to take a shower to wash off this sphincter dust from last night.

sphincter of fire 

The burning sensation you get in your anus the day after eating way too much spicy food.

I jammed an ice cube up my ass trying to extinguish my sphincter of fire.
