Grinder - The stories go, that ship workers in Rhode Island, especially those who cut off and smoothed rivet heads, were called "grinders". The "grinders" often ate a sandwich from the local deli; long roll, meat, cheese, mayo, etc. Grinder got attached to the sandwich name.
Whatever they're called, they are good eatin'!!
I think a grinder here is a hoagie heated in an oven.
