The exact source of this Japanese line is not documented, so it circulates online mainly as a standalone reaction clip rather than as a quote tied to a confirmed scene. Its appeal comes from the disgusted questioning tone, which viewers recognise instantly even without subtitles. Editors reuse it for reveals involving dirt, stains, strange objects or anything that looks off, letting the voice do the judging for them. Because it is short and self contained, it works in anime edits, meme compilations and everyday chat videos without needing any setup or context beforehand.
