The line comes from The Matrix, released in 1999, when Neo, played by Keanu Reeves, receives martial arts training through a direct download into his mind and calmly announces that he knows kung fu. The moment became one of the film's most quoted scenes because it turns an impossible skill into a simple statement of fact. French audiences heard the same line in the dubbed version, and the short clip later circulated online as a reaction sound for sudden confidence, fake expertise and overconfident challenges.
