PewDiePie, the Swedish YouTuber Felix Kjellberg, made 'Nailed it!' one of his signature catchphrases across years of Let's Play commentary and challenge videos. The line became shorthand for a clean success, ironic or genuine, and fans began clipping it into meme edits and soundboards. Because PewDiePie's commentary shaped a whole era of gaming content, the phrase carries instant recognition for anyone who grew up watching his channel. It remains a go-to celebratory sting in edits today.
