sphync 

When you and a distant friend's sphincters become synchronized and you end up taking a dump at the same time.

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.”

Sphinctacular

An anus that is extremely tight and grips any object inserted into it.

My mistresses ass is sphinctacular compared to my wife's gape.

Sphinctaphone 

A telephone designed to be hidden in the anal cavity and dialed using the sphincter muscles, a must-have for the prison environment.

Luckily I will be able to call home whenever I need to, thanks to my sphinctaphone.

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.
