ebonics.

It drives me nuts too, but not really any more than some other dialects. Listening to some of the accents/dialects from the Northeast are very grating (New Jersey, Philadelphia, Boston, New York) and even some of the stuff you hear in the South.

I work in IT, and most of the folks that I work with in my field are pretty intelligent, but I've got a guy that sits near me that is very "country". He grew up in a very rural area near Houston. I hear him on the phone with people daily say "posed ta" (country for "supposed to").

It's a cultural/regional thing.
