A true hero, you say? Rather, a true hoagie!! :D See what lengths people go to when appropriate to speak the language or dialect of an unfamiliar place? Not at all difficult when the effort is made. I'm actually from western Massachusetts, and I refer to such sandwiches in my everyday lingo as either "subs" or "grinders." They may be used interchangeably, often a "grinder" to some means a submarine sandwich with toasted bread. A rose by any other name would smell as sweet. I prefer to use differing terms when in a particular destination, as I would call a sub sandwich by the "proper" name in Philly a hoagie. Also, a steak sandwich with cheese a cheesesteak. When in Rome, do as the Romans do.
