"I do say "fixin’ to", "y’all", and "Coke"" almost every day and I enjoyed the Wisdom listed at the beginning of this thread.
I also am a raised in the south gal at least off an on until I was 16 then we moved here permanently. I have lived in England, France, Idaho, Texas, Georgia, New York (etc.) and have been proud of my southern heratige. Therefore, I can poke fun at myself. Note that I say myself, and I would certainly not poke fun at others.
I don’ know how one could not say "fixing to, or y’all" without a Southern accent. They seem to go hand in hand.
I don’t think that anybody could have been more Southern than my grandmother or grandfather (both dirt poor from Southern TN and came to Huntsville via a wagon and worked in cotton mills most of their lives, but I could have not loved them more if they were "gentry".
One thing about Southern people is that we have thick hides and can laugh along with other, but we don’t take to people laughing at us.
Remember, the South will not Rise Again, it has already Risen.
