This sound comes from League of Legends, Riot Games' multiplayer online battle arena title first released in 2009. The announcer line became familiar through countless matches, streams and esports highlight videos, where multikill calls help mark major plays. Over time, Triple Kill spread beyond the game into meme edits and short-form videos because the phrase is clear, dramatic and easy to match with any three-hit sequence. It remains popular with creators who want a quick gaming shorthand for escalation and dominance.
