In Japanese, biri biri is the onomatopoeic word for the tingling, crackling feeling of an electric shock, which is why the phrase doubles as a name for this kind of zap sound. Short electric crackles like this have long been a staple of cartoon and anime sound design, where a brief buzz can sell a shock without any dialogue. Online, creators adopted the same shorthand for memes, edits and reaction clips, using it to signal surprise, embarrassment or a sudden jolt. Its brevity and instantly recognisable texture keep it useful for fast-paced short-form video.
