fuckukery 

(fuh-cock-er-ree)

noun

Used to describe something that has been messed up with to the point of no return, or obviously completely made-up. Usually happens in order to make one appear either knowledgeable on the subject matter, or completely blameless in a messed up situation.

Jeremy got so fed up with Michael's fuckukery on Facebook that he posted STFU on his wall one day.

Your lawyer's legalese fuckukery won't erase the fact that you're so going to fry.

My brother's high blood pressure is a direct testament to the level of his current fuckukery.
