Acronym of the phrase, "...the fuck? Shut up!" Formed by eliding the word "what," as in "
What the fuck? Shut up!"
Some definitions attribute this wording to Yoda, of Star Wars: "This is how Yoda would say STFU" (acronym for "
shut the fuck up"). However, this definition is obviously borne of an incomplete
understanding of the Yoda speech pattern. A moment's reflection will confirm that Yoda would say, "The fuck up, shut," or "Up the fuck, shut."
