This sound is associated with the Boo enemy in Super Mario 64, Nintendo's 1996 platform game for the Nintendo 64. The Boo laugh became familiar to players through haunted levels and ghost house moments, then spread into meme edits, retro compilations, and gaming soundboards. It still gets used because the clip is short, recognizable, and expressive without being too intense. Creators often pick it when they want a classic game ghost sound that feels playful instead of fully frightening.
