It's the frakkin' truth! - Nothing to See Here — LiveJournal

11:53 pm - It's the frakkin' truth!

So, I was writing it as "frak", and crankyfool opined that it was "frack". Well, I've sort of been using the two interchangeably, but I really wasn't sure about the whole 'c' thing. I was dubious about it. I had a bit of a look around, but it was actually crankyfool who disproved his earlier assertion and confirmed my suspicions. He found the following two sources:

1. http://www.battlestarwiki.org/wiki/Frak (from the fan perspective)
   
2. http://blog.scifi.com/battlestar/archives/2005/02/ (from Ron Moore's blog)

So. It's definitely "frak". The adjectival form appears to be "frakking" (actually, wondering about the adjectival form was what originally had me rethinking spelling a while back).
