Weird thing is I grew up on Long Island and now live in New Jersey. You can count the people who live in NJ who say “Joisey” on one hand. The accent seems to only exist in some television writers mind. “Lawn Guyland” on the other hand is the accent that doesn’t die.
I think Joie Zee was always more Fort Lee to Weehawken and Hoboken to Jersey City to Newark Bayonne and out to maybe The Oranges or Passaic in the old days
Maybe parts of the Shore too
Today tunnel and bridge Jersey is hipsters who can’t afford or don’t want to spend for Manhattan
But it’s still not what I’d call inexpensive
