      Not so much made as highly dependent on context. Ie, it depends what you’re nodding towards.

      But up and down… yeah, they’ve been pretty universal wherever I’ve been. Kinda cool, really!

      Yeah, my understanding is that the side depends on context but also eye movement, like with the “check that out” you can move/roll your eyes to the side you’re pointing to to signal that, while the “come over here” is a quick move to the side you’re pointing and moving back to the center

      You can also count mouth movement too but that depends on the person, some faces are rock solid and don’t move unless they talk and some are doing all kinds of facial expressions

        Up and down is “guy code” but side to side is just universal “look/go over there”

      Up and down are reversed for black dudes. I hope this can clear up communications between the races.
