Chainsaw sounds have been a staple of horror and comedy editing for decades because the revving engine is understood instantly, even without an image. This nine second version circulates on soundboards as a quick reaction clip, shared for Halloween videos, slasher parodies, lumberjack jokes and over the top DIY fails. Its appeal is simplicity, a single recognisable machine noise that signals chaos, danger or a very bad decision. Creators keep reusing it because it works muted as a visual gag and loud as a genuine scare cue.
