The phrase comes from everyday casual speech, with 'rn' as texting shorthand for right now, and the clip circulates online as a short reaction sound rather than a quote tied to a confirmed public source.

Short spoken denials like this spread easily in edits because they are instantly understood, easy to caption, and flexible enough for food videos, gaming moments, group chat jokes, and ironic appetite posts across social platforms today.
