Usually used when someone is PISSED AS SHIT! Utterfuck is also a word describing when someone is titty-fucking a cow. This originated when Wolfgang Amadeus Mozart was preforming an extremely bad ass concert which the queen of England was attending.
Mozart decided he wanted to make his performance the best he had for the queen.

In short he titty-fucked a cow.
