in prison lore, jody is the guy who makes time w/ the wife or girlfriend the con leaves behind while he does his time. but why jody, not a particularly masculine or even sexy name, like mac or giovanni. in hispanic jail circles, i think he’s sancho. where did jody come from?
It comes from “Joe the Grinder”, apparently.
thanks! now it makes sense.
I questioned the masculinity of Jody too when I was serving in the armed forces. I kind of felt he was a worm, and I would squish him upon my return.
The link was interesting. And I am glade. and give thanks that I didn’t know prisoners heard the same thing 
FTR, I’ve never heard a cadence called a “jody call”. I’ve only heard cadences about jody called “jody calls”. Minor nitpick.
Got nothing to add to the Jody thing.
But in a somewhat similar vein.
Went to Parris Island in August of 1966 and it was always Jody doing his thing with your girl friend, miss Rosie Rottencrotch.
