Pentakill is best known as an in-game announcer call from League of Legends, where it plays when one player secures five kills in rapid succession. The term itself predates the game in competitive multiplayer culture, but this version became widely recognized through match highlights, livestreams and montage edits. It remains popular because the word is short, the delivery is instantly dramatic, and viewers immediately understand it as a signal for complete domination or a perfect finish.
