"Coon" down here means "Coon Ass", which means someone from Louisiana.
My sister's husband calls himself a Coon Ass with pride, as he should.
Shuck them crawdads, baby!
Yeah, and I get screamed at and flamed every time I use it in the Cajun context - as in "he's coonie" or coon-ass anything. Otherwise, I think it's an atrocious word in the "n" word category.
