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.

When instead of wiping your ass after shitting, you push your penis through your legs and piss on your asshole, successfully cleaning yourself from left-over feces residue in your ass-crack

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.

sphincter grease 

sphincter grease /ˈsfɪŋktər - grees (n.):

1. The resulting oily residue as having been rendered from an abnormally abundant and unkempt conglomeration of "swass" (aka. ass sweat).

-This advanced state of natural anal lubricant can typically be found on most hippies, destination vacation attendees, and hobos, and is commonly noted as the 2nd natural state of anal condensation, the first being "swass" and the 3rd being "ass butter." Sublimation is possible in extreme cases, however highly unlikely as sphincter grease plays an integral role in springboarding swass into a semi petrolic, pre-gelatinous state necessary for the achievement of ass butter.

I wouldn't be sliding all over this god damned linoleum car seat if it weren't for all this fucking sphincter grease

Radar Sphincter

The almost magic-like phenomenon when someone who needs to take a really bad poop gets within 20 feet of a toilet and immediately they have an almost uncontrollable urge to crap.

Dude I was flexing like Mr. Universe on that road trip and when I got into McDonalds my radar sphincter went off and my turds were coming out like people in a burning building.
