Nod of Acknowledgement 

Something done primarily by males who are in the same demographic.

A simple nod that a guy that gives to another guy that acknowledges the fact that they are both aware of each other and accept each other's presence. Usually done without any thought going into it, essentially a non-verbal message of acceptance.

I have no idea why we do this now that I think about it, it's like some primal need to tell each other that we aren't hostile. Maybe it has to do with alpha males or something, left over monkey shit like arm hair I guess.

*guy walks down hall by himself*
*second guy walks in opposite direction*
*look at each other and give a brief nod before passing*

Cleetus: What should we name our country? Cleetusistan? United States of Cleetus? What should we call it? Should it be ACKistan?

nod of acknowledgement 

The nod of acknowledgement is a standard among guys as a way to let the person know that you see them, without having to resort to using words. Girls will generally not accept the nod of acknowledgement and opt for a wave of the hand and/or a smile, perhaps even accompanied by words. The nod of acknowledgement is a wordless conversation.

The only acceptable response to a nod of acknowledgement is another nod. If you speak, you have broken the point of such a gesture.

Situations in which the nod of acknowledgement may be used:
(1) Walking past a friend to class
(2) Catching a friend's eye across the room to say "hi" without verbally saying it
(3) Giving approval of a friend's actions
