Bloodlust began as a shaman ability in World of Warcraft, granting a whole party or raid a temporary haste increase at a crucial moment in a fight. Because raid leaders often call for it just before a boss burn phase, the sound became closely linked with coordinated pushes, clutch kills, and high-damage windows. Clips from raids, streams, and gameplay montages carried it beyond the game itself, and it remains a shorthand cue for gamers signalling that it is time to go all out.
