This sound is known online as a Katarina quote from League of Legends, the long-running multiplayer game by Riot Games. Katarina is one of the game's most recognizable assassin champions, and her short, self-assured voice lines spread easily in clips because they fit highlight culture so well. The quote stays popular in gaming edits, especially for montage moments, smug reactions and posts where someone succeeds with a risky play and wants a concise, confident punchline.
