I'm from Georgia so yes, all soft drinks are cokes.
I've noticed just about everyone says ya'll now so you really can't tell where they are from. I heard it the other day with someone from California. When we lived in Ohio and everyone said you guys my brothers would say ya'll guys.
My Daddy used to say "like Pete O'Neil" He used ole Pete in all sorts of way. Look at him sittin there bigger than Pete O'Neil. To this day I have no clue who Pete was.
There are a lot of regional differences here. For me the mid-day meal is lunch and the later meal is either supper or dinner. Hubby's from south Georgia and dinner is lunch then supper is the late meal. He has been up here in Athens so long a number of times we have been late to special meals because his family would invite us for dinner and he would think they meant supper.
I'm often madder than a wet hen. And my son often aggravated the hound out of me. Daddy would often threaten to whup the livin tar out of my brothers. He also often wondered what in tar nation they were up to. Evidently those boys were often in tar.
Mama was from the north Georgia mountains and Daddy from middle Georgia so their accents were totally different, they ate different things and both had different expressions. Mama's daddy used a lot of Scots phrases, I'm guessing that was a mountain thing. We kids just learned to be great translators. My ex-husband was from a rural area so it took me a long time to figure out half of what he was saying.
The first time a British person called Daddy a yank (we lived in Saudi Arabia for a while and there were a lot of Brits there) Daddy bout took his head off.
