Sounds like this spread through TikTok and short-form video reposts, where animal clips that seem to swear are shared for their shock value. The swan clip became a reusable reaction because the honk is short, instantly recognisable and easy to drop over unrelated footage. It sits alongside other accidental-swear animal sounds and unexpected voice-like noises that creators use as memes. Because the effect relies entirely on what viewers think they hear, it keeps circulating in edits, compilations and soundboard collections long after the original animal video itself has been forgotten by most viewers online today.
