Artist Stare

A term used to describe when a person, most likely with a history in fine arts, stares at a person for an uncomfortably long amount of time, and may even appear angry. In reality they are squinting at a person's features trying to figure out their proportions, without realizing that they are doing so.

Person A: "Mr. G kept staring at me yesterday, I think I'm in trouble."
Person B: "He does that to everyone, he has 'Artist Stare syndrome."
