“Oops!... I Did It Again” is a Britney Spears song released in 2000, and the title line became one of the most recognizable pop hooks of that era. Online, short clips of that lyric spread in edits, reaction posts, and meme videos because it instantly signals repeated failure or knowingly bad decisions. Its staying power comes from how fast the joke reads: even a very short snippet tells viewers that the person on screen has done the exact same thing again.
