I know that it's not near the same thing as this video, but I had a flatmate assigned to me my first year in uni. The guy was an only child from rich, negligent parents, had a sports car and massive speakers in the room. At 18, he had a dream of becoming a drug lord, and have people over at all hours to sell bits of weed. He absolutely stepped over all my boundaries constantly, and 18 year old me had no resources to stand up for myself. The funniest, most annoying shit was when he took some drug concoction (maybe G or K??), and pissed all over the floor.
For sure he's a rich failson now, with a brain fucked up from drugs and covid. A few years ago, a name search would bring up his shitty goa trance music, but not anymore. I hope he's dead.
