I've never seen anything at the supermarket labeled "side meat," so I went looking—

I found this definition in, of all places, The Urban Dictionary:

Side meat

Slabs of meat taken specifically from the sides of a pig, practically a staple in the deep south. May be smoked and cured, in which case it becomes known as bacon, or salted, in which case it is known as salt pork. Sometimes referred to as "side pork," as well, it is an indispensable ingredient for the southern dish of boiled greens.

"Side meat" was mentioned numerous times in John Steinbeck's "The Grapes of Wrath," a story of an Oklahoma family who left home during the Dustbowl years to work in the fruit picking industry in California.

Fry up that side meat, ma - I'm starvin'!

(Google failed with "define:side meat")

Maybe if I lived in the "deep south" I would see side meat in supermarkets. (I'm in Minnesota.)

Of course we have bacon, and I have seen "salt pork," and I think I may have used it in a recipe once.

So, am I to infer that if something is called "side meat," it is not cured or salted? Otherwise it would be called bacon or salt pork?
