This phrase became widely known from YouTube Rewind 2018, where Will Smith opens the video by saying “It’s rewind time.” The line quickly escaped the original upload and spread across meme edits, reaction videos, and parody compilations, often used to introduce a fake do-over or a sarcastic flashback. It stayed popular because the wording is simple, the delivery is memorable, and the source video became a major online talking point. The clip is still used whenever creators want to signal a rewind with obvious internet irony.
