Happy Souls is an animated parody of the Dark Souls games, a series famous for punishing difficulty, trial-and-error combat and repeated deaths. The joke behind this line depends on that reputation, because almost nothing in those games feels easy. Clips from the parody have circulated on YouTube and in gaming edits for years, and this short answer was lifted as a standalone reaction. Gamers reuse it whenever a tough fight goes well, turning a series known for frustration into a moment of casual, overconfident humour that other players instantly understand.
