Frack.  Such a dirty word.  We should really be replacing that lone vowel with an asterick.  Forget f*ck (so passe), the new expletive (as inferred by Rolling Stone magazine, Bill McKibben and hopefully one day extremely soon our President) is fr*ck.

To be used as any other expletive, for example:  fr*ck you, fr*ck me, fr*ck that.

Now read the fr*cking article Obama and Climate Change: The Real Story as featured in Rolling Stone Magazine.
