MIL (rural midwest) says "warsh", FIL (urban midwest) say "wash". I know the Balt-Wash warsh, but it's a different-sounding one. And now I wish I had gotten around to learning IPA notation when I was hanging around linguists.

I think of "warsh" as a Baltimore-Washington accent

There should be a map for this! My parents say it and they're from SW Missouri.

wash warsh Wash wish whoosh.

I think it's too bad when people think regional accents sound uneducated.

Also this. Plus they're endlessly fascinating.

My mom was from Saginaw, Michigan. I don't remember her parents or siblings saying "warsh," though, and they all grew up in the same place, more or less. She use to tease Dad about his yooper accent (U.P.-er, aka, from the Upper Peninsula of MI) and he'd tease her about "warsh."

Now I've lived in NC for longer than I lived in MI, and "ah reckon" is as much a part of my vocabulary as "ya, sure, you betcha."

Yep. Although it's fun to see people with accents flip the channel on people who think they're stupid because of an accent or dialect usage.

I find code-switching endlessly fascinating, linguistically, and it's an endlessly useful skill to have. I used in in teaching all the time, to great effect.

But it's really wince-inducing when someone tries to code-switch and they DO IT WRONG. But you see this trope played with endlessly in TV, movies, books and commercials.

ETA: Jebus, could I have used "endlessly" more?!

There are two Rs. They trip lightly off the tounge.

Yes, what Plei said. Two rs - both pronounced. Like the two rs in library.
