From Green Bay to Dickinson, the complete utterance is “Op Sorry.” If one is not in a hurry it is sometimes “Oops, Sorry.”

I say "ope, sorry". Never realized it until I saw the midwest memes.

That's quite a ways.

I'd argue it's not just Green Bay-Dickenson on the east end, but also extending to like souix falls/Fargo on the west end

"Oop, sorry" was viscerally familiar to me
