This laugh is associated with Chucky, the possessed doll from the Child's Play film series that began in 1988. Over time, clips of Chucky laughing spread through horror compilations, reaction videos, and short meme edits because the voice is instantly recognizable even in a brief snippet. It stays popular because it can play two ways at once: as a genuine horror cue and as an exaggerated joke for chaotic or mischievous moments. In meme editing, it often fills the same role as a vine boom sound when a reveal needs extra impact.
