The phrase comes from everyday Russian speech and spread in its slowed form through short video edits and soundboards, where pitched down voices became a popular way to exaggerate a reaction. Slowing became the joke itself, turning normal disbelief into an overlong, almost exhausted response that fits fails, plot twists and awkward reveals. The Russian wording stayed even for viewers who do not speak the language, because the tone makes the meaning clear. It remains in rotation as a ready made stunned reaction that needs no setup or explanation.
