Girl 1: Why does Bryan look like he's going to kill that kid?

We've all heard of resting bitch face, and I think we all know what it means. We would like to recognize other resting faces: people who just can't help but look a certain way without even trying. Our first is resting smug face: someone who just looks smug unless they're trying to look another way, like angry or amused.
That guy is so cocky, he even has resting smug face.
