The laugh comes from Chucky, the possessed doll at the centre of the Child's Play horror films that began in 1988, where the character is voiced by Brad Dourif and known for mixing childlike playfulness with sudden cruelty. Clips of the laugh later circulated on soundboards and in Spanish-speaking classrooms and group chats under the name risa de Chucky, shared as a prank for quiet moments. Its length and recognisable tone keep it popular for Halloween posts, horror edits and reaction videos long after the films first appeared.
