This sound circulates online as a short, meme-ready sad cat effect rather than as a clip from a named film, show or song, which is why it works in so many unrelated videos. Its appeal comes from the familiar contrast between a cute animal noise and an exaggerated feeling of loss, a combination that short-form creators reuse for rejection jokes, failed attempts and gentle self-pity. Because the meow is instantly recognisable and the mood is clear without any words, it has stayed useful as a quick emotional punchline for edits, reaction videos and chat stickers.
