People not born in or near Boston often get confused by a native's accent and although I've successfully tamed my Boston accent (for the most part) my word choices are a dead give-away for anyone familiar with what I like to refer to as "Boston SLANGuage".
The word wicked in recent years (at least in gay circles) conjures up images of a beautiful Broadway musical, but when a Bostonian says the word it has a very different meaning. Wicked, when uttered by a Bostonian (and by the way its said here with a great deal of frequency), is intended as a superlative to stress something. Growing up I probably said something was "Wicked Awesome" a few million times. While it would give my cousins from the mid-Atlantic pause, after a second or two they usually caught on.
