When your "brown eye" (also known as an anus hole) contracts, which causes a closing effct. Once the anus hole opens once more its ends the completion of the "buttwink".
Buttwinks often occur when pinching off a turd while taking a dump or during sexual intercourse (when climaxing for both sexes).
I had to buttwink to pinch off that turd
Dude!, I was having sex with this hot chick last night and she buttwinked when she orgasmed, thats when I decided to try anal.
The little glimpse of a girls butt crack when she is wearing very low rise jeans. This is only the case when she is not wearing panties. Wearing panties makes it a panty wink

When a chick squeezes her arse hole and it winks at you

The feeling that occurs immediatly following an extra large shit, when your butthole contracts as a result of the 2x4 that was just pushed through your 0-ring.
