Jallen 

Describes a teacher who puts 0 effort into his job and disregards the thoughts of his students. Such a teacher praises those who agree with him and fails the rest. Such a man does not deserve his job, and the fact that such a pretentious asshole such as him has a job while far better humans struggle to find jobs is why so few people have faith in humanity.

Dan: Dude I just got called out of Jallen's class today! I don't have to deal with his bullshit today!
Jackson: You lucky fuck!
