Term for someone that acts like they are from Boston, roots for the Red Sox, talks with the accent, but isn't even from Boston or MA.
My friend Jon is such a chowdah. That guy goes on and on about the Sox and the city of Boston, but he's not even from there, now he lives in San Diego AND He grew up in Rhode Island!
