When the penises of 2 dudes in a threesome with a chick accidentally touch.

Joe: "How was that threesome last night?"
Bill: "It was going really well until me and Bob dongknocked. Then it was just awkward."
Jow: "The chick was hot though right?"

Doorknocker

Big hoop earrings, often with the wearer's name in script across the horizontal diameter. It's not uncommon to rock a matching name chain.

"Giirrl, my ears are killin' me from wearing these heavy-ass doorknockers all day; i gotta be stylin' though, you know?"

Syberian Doorknocker 

The act of inserting icecubes in ones partners anus then having anal sex. The icecubes are for pleasuring both partners. The ice is supposed to numb the anus for the receiver making it more comfortable and less painful.

I first heard it on the Bubba The Love Sponge Show.

Marsha: Greg told me he wanted anal sex again, and I told him no because it hurt the last time.

Jan: Well what did do?

Marsha: He suggested putting icecubes in my..... poop-shoot! He called it a Syberian Doorknocker!

Jan: Well did ya'll do it?

Marsha: Fuck yeah. I had an assgasm and I was numb all inside.
