the muscle that makes you poo
i had to get 16 stitches in my sphincter because vitt did me up the arse
ring-like muscle found in the anus
From the South Park song "Mr. Hankey the Christmas Poo"
and won't fall in the toilet
coz he's just clinging to your sphincter
and he wont drop off and so you
shake your ass around and try to get it to drop in the toilet
and finally it does
noun: one's pooper
gentlemen, rest your sphincters!
a muscular ring that closes a bodily opening
I had to shit the runs during the whole date with that babe last night. I kept thinking "Sphincter, don't fail me now!"
the circular muscle in your arse;
"aww that huge crap made my sphincter hurt"
possibly the coolest word in the english language
may hurt during anal penetration
watch out for the sphincter, it might be hard to shit!
