The Schizopost laugh comes from TikTok schizoposting videos, a style of surreal, unsettling meme content built around distorted audio, erratic editing and dark, absurdist humour. Clips using the laugh spread as creators reused it to signal that a video was intentionally unhinged rather than simply funny, and it soon moved beyond TikTok into horror edits, reaction videos and short-form compilations. It remains popular because the sound instantly sets a creepy, off-kilter tone that is hard to recreate with ordinary laughter, making it a shorthand for schizoposting itself.
