F.U.N.! (Fuckin' Uber Nice!)
A loud shout you make when you're having so much fun you forget how to breathe!
F. U. N.! I just beat my friend at video games and I'm still laughing!
F. U. N.! I'm eating pizza at 2 a. m. and I'm not even tired!
F. U. N.! I just got a free soda and I'm gonna drink it all!
