The phrase is Portuguese for a theatrically surprised reaction to dramatic information, and it circulates online as a short Portuguese-language meme sound. It is especially popular with Portuguese-speaking creators, who use it to frame gossip, spoilers and unexpected updates as if they were major breaking news. Its appeal lies in its recognisable tone rather than a single famous scene, so it travels easily between short-form video edits and chat memes. Because the joke is in the delivery, it works even for viewers who only catch the exaggerated emotion.
