CJ, or Carl Johnson, is the protagonist of Grand Theft Auto: San Andreas, released in 2004, and his laugh has become one of the game's most recognisable reaction sounds online. Short clips of game dialogue and laughter spread through YouTube edits, meme compilations, and soundboards, where a one-second laugh is easier to reuse than a full scene. This version is especially popular for ironic reactions, including edits that pair it with solemn or awkward moments, because the contrast makes the joke land instantly. That simple, repeatable timing keeps it in circulation years later.
