Every region of the US seems to have it’s own pet name.
When I was in the Marines, back in the 70’s, we had guys from all over.
One day a few of us were in town and was looking for a place to eat and one guy said he could eat a big ‘grinder’.
We others turned around and looked at him like he was talking gibberish.
All us others were from The South and never heard the term before....................
