Children's Indian greeting and response to same?

must be a regional thing, I have no idea what you’re talking about. where are you from?

I expected this to be a contrived way to ask How?

What region of the country did you grow up? Nor Calif here, and I never heard of this.

Do any of these words sound familiar?

Indians do not have any common languages; each tribe’s language is quite different, and often not even close to the language of their nearest neighbors.

Most of the Native Americans I know generally respond in English though ;)

I suspect that the words were simply made up like most children’s camps do.
