F.U.N.G 

Youngsters from modern society who don't appreciate anything from the past. They take most of what they have for granted. They do not see the beauty in anything from the past. They rely too much on modern day technology. They can't see quality when it's always been there.

"You're part of the F.U.N.G bro..."
