when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.

FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
