What Is a Serviette?

Stubble jumper refers to when a stock of wheat gets cut across your field. A serviette is French for plate or tree or table. I think it's similar to the American expression, what's good - which means what's out and how are you? So if that one works... Is there a point of origin for this? I know that what's good is black culture. That's where it came from in America. But do you... Right. There we go. We got three right between Michelle and I. Good doing well.
