This sound is associated with Toad, the Mushroom Kingdom character from Nintendo's Mario series. Online, the scream is commonly clipped and reused as a reaction sound for panic, failure and chaotic comedy, especially in short meme edits and gaming videos. Its popularity comes from how instantly recognizable Toad's voice is and how quickly the yell communicates cartoon distress. It still shows up in meme culture because it fits both Mario-related content and unrelated clips that need a quick, funny burst of alarm.
