For context, this is from a cult classic movie called Bespredel (meaning Anarchy), it's a story about a conflict between prison inmates; the majority being the regulars, and a select few who are called "thieves in law" - the-so called criminal elite who are in charge. The regulars don't want to be treated as slaves by the thieves who do nothing but order them around and collect benefits from their work. Long story short, one of the main characters (nicknamed "Stamp Collector" due to his crime) revolts against the thieves, urging the regulars to start a revolution. The elite responds by setting him up and then humiliating him, where the character named Piston depicted on this video does the deed. (Piston himself is a huge meme among slavs due to the brilliant performance of the actor); Stamp Collector kills himself soon after. The regulars find out about that and beat the elite to an absolute bloody pulp, which leads to a massive riot to the point that the military had to be involved.
