There is no widely documented source for this particular clip, so it is best understood as part of the wider online life of the Japanese word kimoi rather than as a line from one identifiable show or creator. The word itself is common slang for gross, creepy or disgusting, and short reaction clips like this one circulate on soundboards and in meme edits because they need no translation to land. Creators reuse it whenever a moment feels off-putting, and its brevity keeps it useful across gaming, anime and everyday reaction content.
