I've heard it all my life while I was growing up in Memphis, so it's no bother to me.
There's only two grammatical errors that get me aggravate: excessive use of commas(as if they were periods), and when people use apostrophes for every plural form of a word(ex: diva's, cat's, pig's, etc.)
I don't know that I've ever heard that, can you use it in a sentence that someone would use it in?
The grammatical error that annoys me most is when someone types that they "should of" done something when they mean they "should have" done something. I really struggle to not say something when anyone types that.
Sorry y'all.
