When a teacher that teaches an elective or other nonsense subject, such as chorus, assigns a large, time-consuming, difficult and mundane assignment in order to make your life miserable. They do this to make themselves feel better about the fact that they teach a subject that nobody cares about, trying to make themselves feel like an ACTUAL teacher. They often do this at a time when it is extremely inconvenient for you, for instance, when your time would be better spent studying for midterms.

Emily: "Really? When I have finals to study for? That is such teaching hubris."
