fucklicking 

In a threesome, when a man and a woman are having sex, vaginal or anal, and the third persos, m or f, licks the cock and pussy, or cock and ass, of the first two.

That was the best sex I've ever had, getting my cock licked as it was sliding in and out of her, the fucklicking was awesome.

fucklebutt 

The ultimate form of the exclamation “fuck!” Used when something very, very, unfortunate happens.

You: “my sister was holding her, and...”
Me: “and what?!”
You: “and they both got run over by a bus and died.”
Me: “that’s a total fucklebutt!”

Fuckleneck 

Also known as fuck knuckle. When you're so fucking stupid knucklehead won't describe you. A complete and total dumbass.

That fuckleneck needs to be slapped.

Brain Fuckler 

A mythical creature that befuddles his unwitting victim by fuckling the shit out of their minds.

Buckle your fuckle

When you buckle your fuckle, you’re getting ready for some shit to go down.

Jon: “Why?”
Bob: “Some shit is about to go down.”

fucklick 

Fucklick is a verb describing the action of licking a fuck, and it also is a noun, if calling someone a fucklick or fucklicker.

It is the act of taking the tongue and sticking it out so as to lick the shaft of the penis as if fucks the vagina. The tongue may also rest upon the labia as the fucklick takes place.

Harry was drilling Abigail doggy-style, when Bernard decided to put down the video camera and give the two of them a fucklick.

James is such a fucklick!
