LOL! When I saw "bubbler," I instantly thought "Hey, is mom'sfolly from Massachusetts too?"
I am Massachusetts born-and-raised, having lived in the northeast coastal corner for all my life (so far). Yet, my Mass-accent is much less pronounced than people around me, and I'm not sure why. I'm more "generic American" in my accent, though my dialect -- the colloquial usage of words -- is very much New England/Massachusetts.
There is still a strong influence from England where I live. The town where I grew up was settled in 1626 or so by people from the Jersey and Channel Islands, and their 11th-generation descendents still live here. I think that many New Englanders drop the "r"s in various parts of words, due to the lingering influence of English and Scottish ancestry that permeates large parts of the region.
Here's an odd idiosyncracy that appears to be unique to people from Massachusetts and southern New Hampshire: the use of a negative verb to connote a positive. Example: "So don't I" (meaning, "So do I"). So don't I, so doesn't he, so didn't they, so wouldn't we...
This is something I've consciously avoided, though, so I grew up not using that speech pattern, though many of my teachers did speak that way!
-We say "wicked" as an adjective that means "very": "There was a wicked big accident on the Mass. Pike..."
-Here in the Boston area, "pissah" (from -- excuse my crude language -- "piss"... "pisser") means "good," as in "That was a wicked pissah consaht! (concert)"
-A carbonated, non-alcohol beverage is called "tonic" (this used to be used everywhere in Mass., but over the past couple of decades, with more "immigrants" from other areas, most people now say "soda," a term that spread here from eastern New York)
Now for some fun with American English....
Do you pronounce bury and berry the same or differently?
How about merry and marry?
Does root rhyme with boot or with soot?
Do you know what a bubbler is?
Is a sandwich on a long roll a hoagie, a grinder or a sub sandwich?
Do you know what a hoosgow is? How about hootch?
Lots of others fit in here too.
