The effect comes from real vinyl technique, where DJs in 1970s hip hop stopped and moved records by hand to create rhythmic scratching. Film and television borrowed the abrupt version as a comic interruption, signalling that a scene needed to stop and be explained. Online, it became inseparable from the freeze-frame meme format, usually captioned with a narrator introducing an embarrassing situation. Short video platforms revived it because the scrape communicates interruption instantly, even with the sound low, which is why editors still reach for it for rewind jokes today.
