Asshole Nod

That moment, when you see your boss at the office, or some old friend on the street, and the person looks you directly in the eye and nods without saying a word because they are too much of a coward to speak or apologize for being a utter douchebag at some time in the past.

Dude: "Hey bro did the bossman come talk with you?"
Me: "No dude, he just sort of gave me the Asshole Nod."

Dude: "Wtf is wrong with that guy, he's such a douche and a pussy?"
Me: "Word"
