Capitão Caverna is the Portuguese name of Captain Caveman, a Hanna-Barbera cartoon character introduced in the late 1970s. The character became well known in dubbed broadcasts across Brazil and other Portuguese-speaking audiences, which helped the scream stay memorable long after the original series. Online, the grito survives in short meme edits, nostalgic posts and reaction videos because it is instantly loud, recognisable and funny even when used out of context.
