Person2: Fuck you, I can say fuck as many fuckingtimes as I fucking want you fucking fucker.
Person2: Fuckdiddilyfuckingfucktasticalyfuckinglyfuckillitylefuckityfuck.

Extension, inspired by Ned Flanders, of the commonly used word "fuck"
Adds emphasis and humour to an already overused word at the cost of it's sometimes offensive nature.
(It still should be considered unwise to use in front of in-laws, teachers etc.)
Kid A - "You have squashed frog between your toes!"
Used when you really haven't done anything recently; a completely uselessday. A day/time period where not only did you not get any work done, but you didn't even get to do anything you find entertaining.
Person 1: Hey man, what'd you do today?
Person 2: Fuckdiddlysquat. All I did was go over to my in-laws and listen to them berate me on how lazy I am, then I went to a very distant acquaintance of mine's party out of obligation and there wasn't even any alcohol or girls. Waste of a day.
