Southern California city where apparently all the white trash and their many children from Fontucky and surrounding high desert areas moved to when their plumbing, contracting, monster truck driving, or whatever other bumpkin jobs paid off and they could afford (or at least pretend to afford) an $800,000 house. If you are a hillbilly and do not know what nice really is, Rancho Cucamonga is the town for you.
Sometimes referred to as Rancho Cucaracha.
Conversation between two toothless emo boys from Phelan:

Boy1: I hear next year's gonna be a tv show what's called The RC about a bad kid from Wrightwood that gets adopted by rich folks in Rancho Cucamonga. You know like that OC show but better.

Boy2: Yeah, it sure is nice in the RC. One day when our meth lab is up and runnin' and we're makin' a hundred dollard a day we're gonna move there!
