This effect comes from the world of darts and Autodarts, the automated scoring system where cameras track darts on a standard board. A bounce out happens when a dart hits a wire or another dart and falls instead of scoring, producing that distinctive metallic hit. Clips of the sound circulate on soundboards and in short sports edits because the ping is instantly recognizable to players. It remains popular as a quick audio cue for failure, bad luck or a shot that looked good until the last moment.
