Ironically, there is an historical link between the culture and lingo of urban blacks and the culture and lingo of deep south rednecks. The paths have diverged since the migration post WWII, but the linkage is there.
For example: if you want to see men drinking beer sitting on a cloth upholstered sofa on the front porch in the city, where do you go? If you want to see men drinking beer sitting on a cloth upholstered sofa on the front porch in the Southern Piedmont, where do you go?
hm? The porch?
Did you know that “porch” is a word derived from African slaves? At least, this is what I’ve been told...

Not only rednecks:
The “upper class” white senior citizens from rural areas around Charleston SC speak with an accent that I find hard to distinguish from black English.
