dimbulb fv¢kw€€d
A very stupid person.
The way that "fuck weed" is spelled, "fv¢kw€€d" bypasses the onboard censors found in many online BBSs and forums (or fora if you want to be a dick about it).
{I " heard" this totally fictional, fake, phoney-bologna song while I was flying my UAV this afternoon; sung to the jingle for Bob's Discount Furniture):

Bob's Bob-O-Pedics
From your bunghole to your penis
Some dimbulb fv¢kw€€d broke the carafe!!! (pron. as though it were spelled, "carafay")
{~1.5 second pause}
Bob's Bob-O-Pedics!
