1. One who wants to massively fuck you over and
see you suffering in exams, life etc. Gets a sense of
schadenfreude, without caring what other say, no matter what.
2. Self-assured person who has cultivated being a
dick to the highest level.
That
teacher is a straight cut
dickhead, none of his exam questions can be answered from his notes, and he makes us spend
3 months learning irrelevant bs in class.
