Little is documented about who first recorded Ow Sergio or who the original Sergio was, so the clip circulates mainly as a standalone WhatsApp style voice note rather than a scene from a film or show. Copies are usually numbered, suggesting a small set of similar callouts shared between friends before reaching soundboards. Online it survives because the name and the drawn out call are easy to reuse out of context, turning an ordinary shout for attention into a reusable reaction for chats, edits and meme videos across Portuguese speaking communities.
