Quadra Kill is an in-game announcer phrase from League of Legends, Riot Games' multiplayer online battle arena released in 2009. The line became familiar through years of ranked play, esports broadcasts and montage videos, where players used announcer clips to mark standout moments. It remains popular because even people who do not actively play LoL recognize it as shorthand for being one step away from a full team wipe, similar to other classic competitive game callouts such as Enemy Spotted.
