A form of fourth wall breakage, an Aside Glance occurs when an actor gives a brief, silent glance to the camera as a way of acknowledging that their current situation -- or the person they're speaking to -- is stupid, weird or otherwise unusual. It's generally used as a way to acknowledge the audience's assumed reaction and show that the glancing character is just as smart as them and just as aware of the absurdity of the situation. Importantly, the glancer should never speak to the audience, nor should the other characters (if it is fiction) acknowledge that the person just glanced away.
