fucklebutt 

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

Me “I’m sorry...”
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.

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

fuckless fuck

An anticipated sexual romp, replete with all of the physiological signs, that winds up not being one at all.

It all started out on fire but then mysteriously fizzled into the fuckless fuck when we reached our destination.

fuckable 

If you know that “to fuck” a person is to have sex with him/her, you automatically understand that a fuckable person is one that you would like to fuck. Accordingly is an unfuckable person a person that you don't want to fuck at all. A refuckable person is a person you would like to fuck again, while an unrefuckable person is one that you don't want to fuck again. You know the meaning of all these words by virtue of your knowledge of the individual morphemes fuck, re-, -able and un- and the rules for their combination.

Look at her, so god damn fuckable!
