Gueizão is a Brazilian internet meme clip built around one shouted word in Portuguese. It circulates mainly on soundboards, WhatsApp audio forwards and short-form meme edits, where creators use it as a comedic accusation or reaction to flamboyant, dramatic or suspicious behaviour. The clip survives on its punchy timing rather than any story behind it: because it is under a second long, it works as a quick tag at the end of a joke or the reveal of a prank. Its usage is almost entirely within Brazilian meme communities and Lusophone meme pages.
