I’ll try again. People born in Alaska (or who have lived there for many, many years) are sometimes called “sourdoughs” or “native Alaskans” (as opposed to Alaska Natives, which is the collective term for indigenous peoples). Newcomers used to be called “cheechakos”, which originally meant a newcomer to the gold mining areas, but now applies to any new person. “Outsiders” is also applied as a derogatory epithet for people who are new to Alaska but are generally either arrogant or think they know more than they do about the place.
Doesn’t really explain awesome movies about Mexican culture though.
Are you referring to the 2017 Pixar movie? Man, that one was excellent and earned its Oscar. The daughter being named Coco wasn’t related to the plot or her cultural savvy, though, AFAIK.
“Shortbread and tartan” has been used for that sort of performative “Scottishness”.
Trying to think of an equivalent for Englishness, but what comes to mind tend to be old and outdated class denominators, like "huntin’, shootin’ and fishin’ " for a certain sort of country landowner.
If there isn’t an existing term, maybe we can make one up. How about Poutine-eater…
The British comedian Jimmy Carr refers to himself as a ‘Plastic Paddy’, but in his case, it means just the opposite. He was born in London, raised in Buckinghamshire, and is thoroughly English in culture and accent; but his parents were both Irish immigrants, and he holds an Irish passport as well as a British one.
I’ve also heard “heather, haggis, and hairy knees”; that one seems to go back to Harry Lauder, one of the creators of the music-hall Scot.
