Are they myths? Everything else like the bad drivers and Dunkin Donuts everywhere are completely true, but in the 21 years I've lived here, I've known less than five people who had anything resembling the accent—everyone says "park", not "pahk". Only "slang" people use are things like "the T", "the cape", and others that refer to particular Boston-centric things. Nobody uses "wicked" ever. One time my 10th grade English teacher showed us a bunch of "common" Boston slang we "should" know, and absolutely none of us heard any of them before.
