gentlemen, rest your sphincters!

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

i had to get 16 stitches in my sphincter because vitt did me up the arse

"aww that huge crap made my sphincter hurt"

omg sphincter!!!!
watch out for the sphincter, it might be hard to shit!

I had to shit the runs during the whole date with that babe last night. I kept thinking "Sphincter, don't fail me now!"

1.if u tickle my bumhole, i may poop, or fart
2.I was peeing and my sphincter caused me to flatulate
