1 definition by Nordo

 
1.
A dialect typified by a non-rhotic speech pattern and a merger in the vowel classes found in words like "cot" and "caught."

For the record, I've never heard anyone say "Bahsten" or "Sahx," apart from people faking the accent. Most people from Mass or New Hampshire will say "Bawstin" and "sawx."
A Boston Accent would best be used as follows: "Yoah retahded if ya don't think the sawx ah frickin awesome."
