Estourado is Brazilian Portuguese slang for audio that is blown out, clipped and pushed past its limit, which explains the name and the harsh volume of this Makita tool recording. Makita drills and saws are common on building sites, so the raw mechanical noise is instantly familiar even before the distortion makes it a joke. The clip spread through Brazilian meme edits and WhatsApp shares, often alongside other oversized punchline effects like the vine boom sound, where being far too loud is the entire point of the humor.
