The exact original recording behind this distorted laugh is not clearly documented, which is common for short clips shared and re-edited across soundboards and social platforms. Instead of coming from one famous scene, it has spread as a reusable effect, passed between creators who slow, pitch down and distort ordinary laughter to make it sound sinister. That flexibility keeps it useful: it fits horror edits, dark comedy, Halloween content and reaction videos without needing a recognisable character or quote, and its unsettling tone makes a brief moment feel much more intense.
