If the Jewish accent y'all talking about is turning bird into boid like Indiglow made an example of, or like you said Jersey into Joisy. I knew an 80 year old preacher from Alabama who would pronounce first as foist. That sound like some shyt we would associate with an old timey Jewish NY accent. I'm sure that man never stepped foot in New York. Maybe that was just some old time American shyt that was stronger in NY.
They got some of this in east Mississippi and west Alabama too. My grandmother's sister used to pronounce Michael Jordan as Michael Jerden.
yeah that's that mid South shyt Fr Fr. And can't forget "mane". Midsouth shyt. I wonder how mane got to the Bay? Prolly by way of St. Louis and other parts of the Midwest that's on that, migration shyt. I know the bay and Midwest got some type of connections goin on.
