troutdouche

A troutdouche is traditionally a teacher who is intentionally unclear in their teaching. In fact, a troutdouche may even make up much of their material.

A troutdouche's assignments are unnaturally difficult and will probably mindfuck you. Such assignments require too much effort for how little they influence your grade. You know you're in the presence of a troutdouche when students band together and create "Down with the Doucher" clubs.
