I just noticed that when you do The Nod™ to other men, you nod up if you know the person and you nod down if they are strangers.

An astute observation.

I'm not a man but I do the Nod: smile and nod down.

I only nod up if I want to talk to the person.. It has a kind of challenging undertone I guess. If you do it really hard and multiple times it can also be understood as a taunt or challenge to fight.
Nodding down is more going towards a bow and shows respect or non-aggression.

Who does The Nod™ to strangers?

@daintycode you don't? To what depths has humanity sunken? :P

In a class where we learn about communication stuff and differences between countries, the professor made us realize that the nod down is a slight remnant of the time we had to do a reverence in front of noble people

You nod up to a stranger that's eyeballing your woman, that's for sure.
