Boston Artistic 

Autistic- As derived from the regional pronunciation of the North Eastern United States (Most predominantly in the areas surrounding Southern Boston) in which the letter "R" when preceded by an "A" is often unpronounced and replaced with the sound "Ah" such as car (Cah), bar (Bah) and in this case Artistic (Ah-tistic).

Mary O'Boston: You should meet Tommy, he is wicked autistic.
Danielle California: Oh I am so sorry to hear that!
Mary O'Boston: Me too, he will nevah make any money at it.
Danielle California: Wait... Autistic or Boston artistic?
