It when a word is divided by two, and have the word fucking

It's used when your exited, angry, sad, can be used in a lot of situations.
Word fucking word, example:
It's the Xbox fucking 360!
Old fucking man, get out!
It's on the Play fucking station, what the hell do you think, Game fucking Cube? Get out!
Fight fucking club is a great movie.
