I suppose it would have been clearer if I'd typed it out "New York Cidiot" which means someone exhibiting  the common mental debility so prominent in those living in the more affluent and controlling population of New York City who mistakenly believe themselves to be the height of cosmpoloitan sophistication when they are among the most narrowly ignorant, not only of life in the wider world but even that which lives a few streets away from them within the city.  Alas, Simps is only typical of the type.   I suppose it could be used for other such people who are so daddled with the reputation of the large city they live in, probably about one per country is the limit for that,  I doubt those who live in LA or Chicago who occupy the same niche are unaware of life outside of their city to the same extent.
