Some guy will post a picture of a pretty standard looking pepperoni pizza and say: "Imagine not living in new york." And then there's the whole bodega discourse, which is also funny. "For you non-new yorkers, let me explain: a bodega is not a corner store. It's a place where you can buy gatorade, toilet paper, AND eggs." Thank you sir for explaining that to a slack-jawed yokel such as myself.
I think a lot of the more obnoxious aspects of that discourse comes from transplants who are either trying really hard to be seen as a real and authentic NYer, or grew up in a suburb of a city whose downtown they barely visited, and now see common features of walkable urban cores as unique to New York.
Sounds a lot like tryhards that want to be very Californian in California. The only thing I could suggest for people that didn't live most of their lives in California and want to fit in without seeming like a poser is to learn how to pronounce some basic Spanish words, especially food items. If you say "caysa-deeah" instead of "kwesa-dillah" you'll be fine.
You can not convince me anyone says this.
I know people that said it like that.
If you want to hear the latter half of that out loud, watch the movie Napoleon Dynamite.
