bro nod 

(N) : When a man nods in the general direction of another man. This can be an ambigious greeting often meaning “hello” or “whats up?”

I haven’t talked to him in a while and I didn’t want to hear about his drama so I gave him a bro nod.

Bro Nod 

A gesture of approval between two guys that believe the other is worthy of bro-hood. Usually between two people who have never met, but can also be used with someone who you don't have time to talk to.

"This guy at the airport gave me a bro nod as he passed by me, you could tell he was a true bro"

Bro-nod 

That awesome moment when you, and a stranger notice a female with a nice body, and give each other "the nod"

*really hot chick walks down the street*
*Guy number 1 sees her*
*Guy 2 sees her at the same time*
*Both guys look at each other and give the bro-nod*
