The clip comes from the finale of Neon Genesis Evangelion, the influential anime series that aired in Japan in 1995 and 1996. In the final episode, after Shinji Ikari accepts himself, the other characters gather around him, clap, and repeatedly say omedetou, the Japanese word for congratulations. The scene became one of the show's most quoted moments, and fans later lifted the audio for soundboards and video edits. It endures because it condenses the series' emotional payoff into a few seconds of pure, unironic praise.
