Here’s some excellent insight into how the Battlestar Galactica writers came up with ‘Frak’ as a replacement for it’s more vulgar cousin F*ck. And they’ve never received a complaint from SciFi owner NBC or the FCC over their word.
Snippets from the story:
It was Larson who first used the faux curse word "frak" in the original "Battlestar Galactica." The word was mostly overlooked back in the ’70s series but is working its way into popular vocabulary as SciFi’s modern update winds down production.
Larson, one of television’s most prolific and successful writers, doesn’t much care for the new series. He used "frak" and its cousin "feldergarb" as alternates for curse words because the original "Battlestar" was family friendly and appeared on Sunday nights. The words fit in with his philosophy that while the show was about humans, it shouldn’t have an Earthly feel.
The word has even appeared in the funny pages where Dilbert muttered a disconsolate "frack" — the original spelling before producers of the current show changed it to a four-letter word — after a particularly dumb order from his evil twit of a boss.
"Dilbert" creator Scott Adams calls the word "pure genius."
When new series producer Ron Moore first introduced "frak" in early scripts, Bamber said the actors were dubious. But as writers expanded its use, they caught on to the possibilities.
"I mean why are we not offended by ‘frak’ because it means exactly the same thing as the other thing?" said Bamber, who plays fighter pilot-turned-president Lee "Apollo" Adama.
