The effect takes its name from Vine, the short-form video app where editors used heavy bass hits to underline jokes and dramatic moments. After Vine shut down, the clip survived on YouTube, TikTok and meme pages, where a single boom became shorthand for disbelief or a sudden twist. It is often paired with a zoomed reaction face or a cut to silence, and its recognisable low thud still signals that something absurd or unexpected has just been revealed.
