The clip draws on Halo, the first-person shooter series that began with Halo: Combat Evolved in 2001 and helped define console FPS multiplayer. Its title combines that game culture with the long-running boom headshot catchphrase, a boast players started repeating after landing a headshot in online shooters during the mid-2000s. Short, exaggerated kill sounds like this spread through gaming forums, early video sites and later soundboards, where a single hit could stand in for the whole play. It remains popular because shooters still reward the same instant, precise elimination.
