Estourado is a Portuguese term widely used online for blown-out or clipped audio. Rather than pointing to one famous source, this kind of sound spread through Brazilian meme pages, WhatsApp shares and short-form edits where exaggerated distortion became part of the joke. It stays popular because the effect is instantly recognizable: the audio sounds broken, harsh and overdriven, which matches chaotic visuals and ironic low-quality humor. In meme culture, it fills a similar role to the Vine boom sound or an air horn, but with a more scuffed, compressed feel.
