No single inventor or original recording is credited for this shouted version, which spread online as a short soundboard clip. Its popularity comes from instant recognition, almost anyone who has played on a long drive understands the joke in under two seconds, so creators reuse it for travel edits, dashcam clips and reaction posts.
