When someone intentionally proplapses their anus and uses the now dangling anus to provide sexual pleasure to their partner by rubbing it in a "pritt stick motion" on their genitals
"You better watch it, I am going to shove this stick up your ass."
Bert replied, " Hey now, you want to threaten me with an anal stickling you had better be prepared to carry it out, hehehehe."
When anal hair sticks from one cheek to the other. Usually caused by poop particles, semen slippage from masterbation, or just plain sweat. Usually very painful to pull apart and can leave a red irritating bump.
Tim told me he had his worst anal stickage of the year after he worked out and had his post workout poop and masterbation session.
