This clip is mainly used online as a Russian reaction sound rather than for a widely documented source credit. The phrase translates loosely to asking what just happened, which explains why it appears so often in short-form memes, gameplay compilations and reposted reaction edits. Its staying power comes from how fast and recognizable the delivery is: creators can drop it over almost any strange, broken or uncomfortable moment and the meaning is instantly clear even for viewers who do not speak Russian.
