Cookie Clicker began in 2013 as a browser idle game by French developer Julien Thiennot, better known as Orteil, where players click a giant cookie to earn cookies and buy upgrades. The simple loop became a viral hit and helped popularise the idle-game genre, with its cookie-clicking sound becoming instantly recognisable to players. Years later, creators still reuse the clip in memes and edits because its simple rhythm is familiar to anyone who has played an idle game.
