Reverse effects have long been a staple of audio editing, created by simply playing a recording backwards, and they became widely shared online as creators looked for quick ways to signal rewinds, flashbacks and dream sequences. On short-form video and meme pages, the effect is now used as a shorthand for something being undone or replayed, because listeners instantly recognise the backwards motion even without visual cues. Its popularity endures because it is short, versatile and works across comedy, drama and gaming edits without needing any specific reference.
