True Nutmeggers have no accent, but yes, the NY, Masshole, VT, NH, ME accents are a bit much. Bronx and Boston are the epicenters of linguistic ear stink on the North American continent.
You left out Rhode Island. I have lived in Texas 14 years and every person I speak to, and I do mean every, askes me where I am from. Most guess New York, Close but no cigar. I was born in Rhode Island and lived there until I was 62. Noone ever said I had an accent. Now in Texas EVERYONE asks. I drop “”R”s” in some words while adding them to other words where they don’t belong. I say Moot Zar Rella, monni gort, rigotta, and cabba ghoul. My son in law finds my accent annoying. The other day I used the words, part and pot in a sentence and they sounded exactly alike. He’s from Michigan, does everyone there sound gay?
