The phrase 'glitch in the matrix' comes from The Matrix (1999), where déjà vu is treated as a sign that the simulated reality has been altered. Online, especially in Portuguese-speaking communities as 'falha na matrix', it became a caption and punchline for videos of strange coincidences, repeated events, and eerie déjà vu moments. Short sound effects built around the idea circulate on soundboards and meme pages, where a quick warped glitch cue does the comedic work of a caption in a single beat.
