One word, one syllable, one million uses. Yes, I'm talking about "Frak" -- the expletive du jour for the men and women who populated Syfy's Emmy and Peabody Award winning series, Battlestar Galactica.

The word became so popular it not only appeared in a smattering of other TV shows (30 Rock, The Big Bang Theory, Veronica Mars, Castle) but also entered the vernacular of fans and non-fans alike.

The importance of "Frak" is a major talking point in the star-studded Syfy 20th Anniversary Special, airing December 10 at 9 p.m, as you can see in ETonline's exclusive clip featuring Jamie Bamber, Katee Sackhoff and Jane Espenson reveling in the iconic term.

"Frak was the best invention, ever," Espenson says in the clip. "The thing I love about it is that you don't have to have fighter pilots going, 'Forget You!' 'Duck You!'" But for Sackhoff, who probably spouted the most "fraks" of all, the word presented a unique problem.
