just wondering...

Probably the first one....but is there such a word in the English language?
 
Neither one show up in the Merriam-Webster online dictionary but I have seem them in print spelled both ways although I believe "frak" to have been more commonly used of the two that I have seen.
 
Yup- just watch Battlestar and you will get your answer!!! And be rewarded with a great show too.
