Mickey Mouse has been one of Disney's most recognisable cartoon characters since his debut in Steamboat Willie in 1928, and his high-pitched voice and distinctive laugh have become part of popular culture. Short clips of that laugh circulate widely online as a reaction sound, especially in meme edits, gaming videos and short-form posts where a creator wants to signal mischief or a sneaky plan. Its appeal comes from the contrast between the cheerful, family-friendly character and the cheeky, villain-style cackle, which makes it instantly readable even without any visual context.
