Little is documented about where the Ruki clip first appeared, and its short length has helped it travel mainly as a standalone reaction rather than as a quoted line from a larger work. Online, short reaction sounds like this spread through meme edits, gaming clips and chat replies, where a single second of audio can carry the whole joke. Its appeal comes from that brevity and ambiguity: listeners do not need context to feel the surprise, so creators keep reusing it whenever a moment needs a fast, recognisable interruption.
