The term comes from Fortnite Battle Royale, where the Fortnite pump shotgun became famous for dealing up to 200 damage on a perfect headshot at close range. Players shortened that play to 200 pump and clipped the shot sound for montages, TikToks and stream highlights. As Fortnite edits spread across YouTube and Discord soundboards, the blast became shorthand for any instant, one-shot elimination. It remains popular because the damage number is legendary among players and the sound alone tells the whole story of a fight ending in a single pull.
