What does Boston call the boton butt?

In Boston, the term "boton butt" is often referred to as the "Boston butt," which is a cut of pork that comes from the upper shoulder of the pig. Despite the name, it has nothing to do with the animal's rear end; instead, it derives from the old practice of packing this cut into barrels called "butts" for storage and transport. The Boston butt is a popular choice for barbecuing and slow-cooking.
