S'crewed (2013)

Graham Young is a dangerously disturbed racist psychopath that lies his way into getting a job teaching at QPIX film school, despite having no teaching qualifications nor any actual talent or skill. A violently two faced scumbag, at home he's a husband to his supportive wife, at work he stalks young men and intimidates talented students into doing poor work, lest their superior talent undermine his own massive inferiority complex. When one bright students politely asks him to stop, Graham begins a psychotic campaign of passive aggressive intimidation tactics, including pretending to be pleasant into front of his co-workers, while being psychotically aggressive and nasty in the classroom. Graham becomes so narcissistically enraged that he actually starts sabotaging the work of students that have figured him out. He spreads malicious gossip to undermine the students he harms, so that the other ignorant staff dont actually bother to do their job and listen to their concerns. Unfortunately, none of the students know quite know how to handle his bizarre tiny peen energy rage. Graham Young truly is a poisonous toxic scumbag. Graham then simultaneously plays the victim so effectively that he convinces dim witted fellow staff members Kerry O'rourke and Lisa Andersen into taking his side, so much that they also engage in aggressively racist behavior. Their idiotic incompetence and Graham's low self esteem and desperately pathetic need for validation leads to a predictably disastrous and violent ending.
