The face that a teacher gives you when she thinks that you did something that is totally against religion

to look fixedly at someone with so much hate in hopes that their face melts, explodes, or caves in with extreme discomfort and pain.

When someone stares at another with a look that makes someone want to shrink down in their seat in terror.

When someone looks at you straight on like they want to kill you or think they are better than you are. They usually have a glazed over look in their eye or they have their nose in the air.
