“I didn’t realize okie doke was actually a phrase. It is Urban slang.”
I doubt that it is “Urban Slang”. I heard it from my mother and grandmother when I was a little kid (very early ‘60s) in rural New Mexico. (And that is about as un-urban as you can get.)
I always thought it came from some TV show in the ‘50s - ‘60s.
You are thinking of okie dokie .that isn’t what he said
