it's a double-edged sword; dialect markers are also used for exposing outgroup members, e.g. how locals can recognize that some visitor is a tourist, possibly even from a foreign nation rather than just the next town over.

I don't know if that's the deal with your example, but a lot of the time, it's just a local accent. Doesn't mean it's wrong.

But yeah, there's this whole language thing where bigger crews start roasting the smaller ones for how they talk and for using some less common words. You see this low-key turf war that, long-term, just kills off diversity. I'm not sure if that's a good thing or a bad thing, though.
