Youins is often substituted for y’all when rednecks test the limits of Darwinian theory. No difference, just a dialect thing. I speak many dialects of Redneckese and I am a Yankee’s worst nightmare. A redneck with an education. I left a mark on most of my college professors.

I know a better way to get rid of them for good but probably cause more damage than good.
