I used it once.

I was about five or six and didn't know the word as it wasn't used in our house. Heard it from one of the kids down the street one day, then used it at the dinner table that night.

Then BLAM! My Dad reached across the table and labeled me with his back hand. That was that. blush

Come to think of it, now, I hear it a lot more from blacks than from whites these days. Hmmmm.
