Not Just For BSG Anymore

Why doesn't anyone say "Felgercarb"? I gather there was a recent ep of Veronica Mars where the characters started using "Frack". (Aside from being Joe Sweedon's favorite show, enough that he even did a guest appearance, that may get me to watch the show right there.) I guess none of the gorram Firefly curses caught on. Except in China of course.
