Mickey Mouse debuted as a Disney cartoon character in 1928 and became one of the most recognisable animated figures in the world, with his high falsetto voice and cheerful laugh becoming a signature part of the character. Clips of that laugh have circulated online for years as a reaction sound, especially in meme edits, TikTok videos and short compilations where a cartoon voice instantly signals silliness. The Hungarian title Mikiegér simply reflects the character's local name, and the sound remains popular because almost everyone recognises it within a second.
