Little is reliably known about who first recorded secten soy anani, and the phrase itself appears to be intentional gibberish rather than a quote from a film or show. It spread as a short shareable audio on soundboards and in chat groups, where users clipped it for its strange wording and deadpan delivery. Because it means nothing clear, creators reuse it as a universal nonsense reaction, similar in spirit to other random meme sounds that rely on timing rather than context.
