Buttwank 

The act of sexually stimulating one's anal region by the use of a dildo. Also refers to anal sex, whether it's gay or not.

The guy from the pen was horny in the ass so he decided to give himself a buttwank by carving a dildo out of a bar of wet soap and beating his ass with it repeatedly.

Buttwink 

A buttwink is when a person flexes their anal sphincter, causing their anus to visibly contract, effectively "winking" with their asshole. Buttwinking can be performed as an obscene gesture, or in a sexual context it can be either a sign of affection or a greeting.

To buttwink, simply use the same muscles used to defecate to flex your anus.

This act should not be confused with mooning (merely exposing your anus) since buttwinking is considerably more rude.

As Sensei Doug walked to his dojo, the rude employees of a strip mall store lowered their drawers, pointed their behinds towards the window, and contracted their assholes to buttwink at the passing martial artist.

Buttwink 

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.
