Pentakill is an in-game announcer call from League of Legends, Riot Games' multiplayer online battle arena released in 2009. In the game, it plays when one player earns five kills in a single streak, making it one of the most recognizable reward sounds in competitive gaming. The clip spread through gameplay montages, esports highlight videos, and streamer edits, where it became shorthand for total domination. It still gets reused because even non-players understand it as the sound of an overwhelming win.
