Yeah, it's dang ancient, not compared to PAC, but ancient compared to me.

I haven't used that term since I was a kid. But we used it to describe a game we'd play during lunch a lot back in high school. It was 21 but with no rules. You'd try to get a rebound or a loose ball and run for your life, shooting a wild shot hoping it would go in before you get clothes lined. We called it jungle ball but I never made the connection to black/inner city BB. I thought the jungle part was a reference to an actual jungle and the dangers you find there.

This brings up another point where does the term "Ni**er Knock" come from?

My parents would never let me use that term so we called it "Doorbell ditching"

It came from the same place that n*lipping, n*rigging, n*rich, etc. came. Colorful expressions from yesteryear.
