In rock and roll, "Hand Jive" I believe referred to a hand-dance and this may have been the title of the song I'm thinking of with the line, "Doing that crazy hand jive."

Thanks for adding to this great thread, Azizi.

I'll ask our Bishop about "talking Jive" in jazz terminology. I suspect there is a musicians' shorthand called this. If so it would be similar to the shorthand bluegrass and oldtime musicians use, to cue each other into key changes, modulations, chord names (numerical Nashville system), verse repetitions, timing of endings, intros to songs, etc.

Or it could be the jazz equivalent of Talking Blues.

All great areas to explore.

But my point is that most genres of music have a shorthand used by players to convey quick info on stage or in jams, unobtrusively. (Even a capella gospel quartets use one, which I have heard in vintage rehearsal recordings.)

A Jive jazz musician might even use the term to refer to playing musician, not speaking at all.
