Methbilly 

Subset of "hillbilly", a lower class of southern redneck often described as "cracked out" or "on the meth". Usually characterized by a lack of teeth and healthy gums (meth mouth), unhealthy body weight, and a supernatural ability to project paranoia via an unstoppable barrage of verbal diarrhea.

I saw Billy Bob the other day. Ever since he hooked up with Truck Stop Rhonda, he's turned into a real Methbilly. All I'm sayin' is hide your cash if that methbilly comes to visit.
