Nathan Fillion: "Double XP Weekend is Rocket Race!! FODRATWATS!"
Nathan Fillion, on his Twitter page, kindly acknowledged my entry work defining his recommendation of the new "in" phrase: "Double Rainbow" on Urban Dictionary! He said it is "Full on." Thank you, Nathan. You are so Full On Double Rainbow, All The Way Across The Sky! (FODRATWATS!)
