Balloon Butting 

Balloon Butting is when you stick a balloon into your anus and then have a friend inflate it to induce sexual pleasure, or you self inflate using a series of tubes/straws.

Hey did you hear that Paul was Balloon Butting?
Ya! It totally burst inside of him and he pooped out plastic!

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.

buttknocker

a)A homosexual, as anal sex is the only form of intercourse for gay men, or
b)An erection in somebody's ass, referring to pulling out and then tapping and wiping the semen on said ass.

Beavis: Shut up, Butt-head! I'm gonna play drums on your nads with my foot!
Butt-head: I'd like to see you try, buttknocker!
Beavis: Don't call me that, Butt-head! (Beavis kicks Butt-head in the testicles)
