This kind of evil laugh is widely used online as a general Halloween sound effect rather than a clip tied to one famous character. It shows up in haunted house promos, seasonal prank videos, horror meme edits and spooky countdown posts, especially around October. Creators keep using it because the meaning is immediate: the audience hears the laugh and instantly expects trouble, scheming or a playful scare. Its exaggerated style also makes it flexible, working for both creepy scenes and intentionally cheesy horror comedy.
