The word had been used with "nodding [such-ly]". If I remember correctly, the person I heard this from was describing one of the attributes you needed to be a manager was to be able to listen to someone and "nod" this way, maybe rubbing your chin with your hand or something to signal to that person that you are listening (even if you're not).
There is even a Wikipedia article about this word, but I cannot remember it at all.
At 58-y.o., this is one of the few times i hear a new word i never heard before (and look it up). Unfortunately, i forgot it right after.
