I'm in Texas and was born and raised here, never left. Same with my mom. My grandparents came from elsewhere. My grandma was born in Oklahoma and her family moved to California when she was young. My grandpa was born in Kansas and his family moved to Oregon when he was young.
That being said, my grandparents and my mother use "worsh" as opposed to "wash" (like I use). For example, "Go worsh your hands" or "He lives in Worshington." Don't know why I didn't end up saying it like them
My grandpa always said Oregon like "Ore-GONE," but down here I always hear it like "Ore-GUN" - which is how I say it.
I've also hear Missouri said "Mussurah" and Mississippi said "Missisip" (edited to add ->) Oh! I forgot, Louisiana as my grandma called it was "Luziana."
Hmmm....let's see...
I must not be a real Texan because I can't say "y'all." Any time I try to make fun of it it comes out "you all." The word (if you call it that) "ain't" hurts my ears to tell the truth, and for some reason when the word "coffee" comes out of my mouth it sounds more like "cwaffy" Try saying it like that in Texas and see how much you're made fun of LOL I get called a Yank (also known as Yankee) more than you know.
I do call every "soda, pop, sodapop, etc." a coke. Doesn't matter what it is. If someone asks you if you want tea you should expect it cold and sweet. People kind of look at you funny if you ask for it unsweetened.
That's about all I can think of for now.
