This quote is associated with Light Yagami from Death Note and is widely shared from the anime's English-language version in short clips, remixes and reaction edits. Online, it became a favorite sound for smug victory jokes because the performance sounds theatrical and absolute, which makes even tiny wins feel hilariously dramatic. It still shows up in anime meme compilations alongside sounds like To be Continued, especially when creators want a clean, recognizable "I win" button at the end of a clip.
