Lots of people have a "well at least we don't talk like those hicks/rednecks/bumpkins/yeehaws/yeeyees" as if the people from there aren't saying precisely the same about you.
There's a fun quiz (though I think it is US only, unforutunately) called How Y’all, Youse and You Guys Talk by the NYT that was eventually turned in to a book with the same idea that is sometimes surprisingly accurate in guessing your geographical situation based on the words and pronunciations you use. https://www.nytimes.com/interactive/2014/upshot/dialect-quiz...
There's another aspect to the discussion as well, which is code-switching. The idea being that you have one way of speaking to, for instance, your friends/family vs coworkers/boss. Some people have gone to great lengths to demonstrate their ire at not being understood in the dialect they were raised on, and many people are shamed by their communities for "being weak" or some such because they "speak white" at work but not on the corner, for instance.
Edit: fun example ->
What do you call something that is across both streets from you at an intersection (or diagonally across from you in general)?
kitty-corner
kitacorner
catercorner
catty-corner
kitty cross
kitty wampus
I would use only diagonal for this
I have no term for this
