I had a work associate who is Boston Irish. "Tic" Boston accent. You needed a chain saw to cut it.
He used to say of a Southern accent - "When I go down there, they all talk funny. When they come up here (Boston), I hear funny!"
The only thing I don't like about a Southern accent is when a Southern woman starts with "Why Bless your heart....". I know I'm in for a broadside!! :-)
I've lived here all my life and I promise you that you've got it wrong.A "tic" Boston accent is an Irish accent.A true "Boston" accent is,in fact,"paak ya cah in Harvad yaahd" or "wickad pissah".
