The record scratch effect comes from the sound of a vinyl record being abruptly dragged or stopped on a turntable. Long before short-form video, editors used it in film, radio, and comedy to signal a sudden halt or a jarring change in tone. Online, it became a staple in meme edits, fail compilations, and reaction videos because viewers immediately understand the joke setup. It is still popular because one very short sound can replace a longer explanation and make a freeze-frame gag work instantly.
