The phrase itself is casual Japanese slang for no longer being able to understand something, and the clip circulates online mainly as a reaction sound rather than as a quoted scene from a named work. Its appeal comes from how easily it fits short-form video, where a single line can summarise confusion without needing subtitles or context for viewers who recognise the tone even if they do not know Japanese. That flexibility has kept it useful for meme edits, streams and reaction videos, where it works as a quick emotional shorthand for giving up on making sense of something.
