The line comes from Team Fortress 2, Valve's team-based shooter first released in 2007, where the Sniper is the long-range marksman class. His Australian voice lines became a familiar part of the game's humour, and this headshot taunt was picked up by players for highlight reels and soundboards. It later spread through short gaming edits and meme compilations, where the calm delivery works as a shorthand for a precise kill. It remains popular because it is brief, instantly tied to sniping, and easy to drop over almost any elimination clip.
