Used to describe a teacher that sacrifices their own students in Satanic rituals to make themself more powerful
Taylor: Hey dude, where's Alex? I haven't seen him in a few days.
Chase: Last time I saw him he left his textbook in English and went back to get it on Monday.
Garrett: Doesn't he know that teacher is collum? His soul is probably in hell right now!
