How has no one mentioned "Shiny," meaning cool or awesome, I know there's Browncoats on this here site. And before you say it's from a show, I've known people to use it in real life, specially since other shows (mostly Castle) started to reference it. Also Frack and Frick as substitutes for the F word. I can't help but feel that I'm forgetting some other TV show originated slang, but that's all I got right now.
