As a WhatsApp audio, this clip belongs to a wider online habit of saving short voice notes and reusing them as reaction sounds in chats, memes and short videos. The phrase itself is ordinary everyday Portuguese, which is why it travels well: it needs no setup and works whenever someone is expected somewhere. With no widely documented original creator or broadcast source, its appeal comes from that shared, informal context rather than a famous scene, making it a handy shorthand for asking where someone is.
