Deja vu clips circulate online as shorthand for repetition, especially in short-form edits where a creator wants the audience to notice that something has happened before. The name refers to the familiar psychological feeling of having already experienced the present moment, rather than to one specific recording. Because the clip is under a second long, it fits easily into reaction videos, gaming highlights, and meme compilations, where it can mark a callback without slowing the edit. Its staying power comes from that flexibility: almost any repeated action, line, or outcome can be framed as a deja vu moment.
