Someone who lives in the Boston area and has a great sense of regional pride, while fitting most of the stereotypes about people from the area to a T. They believe Boston is the best place to live, are fanatic fans of the Boston sports teams, dislike New Yorkers merely because of the sports rivalry, talk with the crude, non-rhotic New England accent, usually are pretty big drinkers, and are often proud of their Irish, and sometimes Italian heritage in addition to their Boston pride. Unlike Massholes, chowdaheads are not necessarily assholes.
Listening to the Dropkick Murphys while driving in your shamrock bumper stickered car, wearing a Red Sox hat and Tom Brady jersey. You're such a chowdahead, Murph.
