As a male, you can perform a quick little nod to another male as a gesture of "Hey, how's it going?", or "Nice car!", or any number of things guys communicate, without even opening your mouth. Men learn this at some point as they grow up. It's not that we, as men, are excluding girls, females simply seem to think that we are either coming on to them, or worse, that we're really creepy.

If a man, were trying to communicate "Hey, nice car" to another guy, he would first look at the car followed by a glance to the owner, then with an approving smirk or smile, he would do the quick nod. The owner of the car would then nod back with an "I Know, thanks" look on his face.


They never have to speak, it's that easy.
