More than merely a semiological experiment, the intention of The F Word is to use a simple, and by itself meaningless, word to alter the tone of almost any text to one with more passion, levity, or angst, depending upon which metaphor you personally attribute to the F word.
By effifying a block of text, fairy tales are more frightening; legal documents are less intimidating; Lacan loses his staunchness and Heidegger isn't so high-brow.
Whichever text you're struggling through, The F Word will, at least, make it a more tolerable read. Type in text or paste entire papers' worth of text. The hope is that the F word will become a little more Fun, and a little less Feared, of a signifier.
Or, just use it for a laugh; that's cool too.
