Only when I'm drunk or stuck in traffic. Otherwise, I have (mostly) rid myself of the typical Masshole traits, at least I'd like to think so. Where I live now is a lot more similar to places in NH/VT than anywhere in or around Boston.
Though I will admit the amount of interest/wonder attached to the Boston accent/attitude throughout the US is pretty funny. I have heard some hilarious interpretations of what people think Boston is like....one girl at @Adventurous 's wedding said "is it true you could be walking down the street and someone will just yell "FUCK YOU" in your face?" Granted that doesn't never happen, but it's also not like a suitable replacement for waving.
I have family in East Boston, Winthrop and Revere. The best accents and hairdos are from Revere.
