Coringa is the Brazilian Portuguese name for the Joker, the long-running comic book villain whose unsettling laugh has become a shorthand for madness and chaos. In Brazilian online culture, clips using that name spread through meme pages, reaction videos and short-form edits, where the laugh is reused as a punchline rather than a direct quote from one scene. Its popularity on platforms such as iFunny helped it travel beyond a single fandom, and it remains in use because the sound needs no explanation: one burst of laughter tells viewers that a situation has turned villainous, absurd or out of control.
