The phrase means “What did you do?” in Russian, and it is shared online mainly as a short reaction clip rather than as a named scene from a film or show. Its appeal comes from the emotion in the delivery: the question sounds less like a request for information and more like an accusation after something has already gone wrong. That makes it easy to reuse across languages, since the tone is clear even for viewers who do not speak Russian. It is commonly dropped into fail compilations, gaming clips and short-form reaction videos.
