I think the worst thing ever to happen to our southern language was when Jeff foxworthy and Larry (the cable guy) came along, in the 80's We were just about to overturn the southern hick accent when suddenly these two characters came along, Not only did they make mockery of the way some of us southerners talk they decided to kick it up a notch by adding their own twist & twang to it, Little did they know our young Red-necks were to idol them, and the trend started, However it wasn't just a passing trend, it continues on today,
I can remember when my son was in his teens, was an animated program called Bevus & Butthead on TV, My son seemingly was inspired by these characters and he and his friend would go around talking like them, ( actually was a good take off of them ) But it drove me crazy with all that huh! huh! huh! and Bungholio something-another,
It was a relief when my son grew up and his friend parted and became distended, However they do still get together from time to time even as adults they still talk like Bevus and Butthead, only now I can find it a bit humorous

. I think these characters will always have a lasting effect on the both of them,
So even though language is inherited from everyone parts of their region, I think some of us are mostly effected by what we hear and watch on TV,
We may innocently start out only mocking what we hear but then it ultimately becomes a way of languages,
