The available information for this clip points to it being a standalone creepy laugh rather than a line tied to a confirmed movie, show, or game source. Sounds like this often spread through meme edits, horror shorts, and prank videos because they instantly change the mood without needing context. Its appeal comes from how a simple human laugh can feel more disturbing than funny, which makes it useful in reaction content, spooky posts, and short-form videos built around awkward or eerie timing.
