The exact recording behind this clip is not widely documented, so it is best understood as a piece of Russian internet slang that travelled through soundboards and short-form video rather than a line from a single film or show. The phrase itself is a coarse, everyday way of dismissing something as nonsense, which is why it works so well as a standalone reaction. Editors reuse it because the meaning survives even for viewers who do not speak Russian: the tone and timing signal disbelief, and the clip has kept circulating in meme edits, streams and reaction compilations.
