Okie dokie smokey

I was recently told that the term "okie dokie smokey" was offensive to African Americans. Does anyone know the origin of this saying or why it is offensive?

The "okie dokie" part wouldn't be offensive. It's just a jovial elaboration of "ok." But "smoke" is an offensive racial epithet, and even in combination with the jokey rest, inappropriate language.

Smokey makes me think of CB language -- a state trooper. Refers to their Smokey Bear hats.
