This audio is widely used online as a Portuguese panic reaction sound, especially in meme edits, short videos and reposted chat-style clips. Its exact source is not clear from the available information, so it is best described by how people use it rather than by a claimed origin. The line spread because the delivery is instantly understandable even in a very short clip: fast, fearful and dramatic. It stays popular in reaction-style humor for videos that escalate suddenly, similar to a scream meme or the RUN vine kind of timing.
