The sound comes from Minecraft, where Steve is the default player character and creepers are hostile mobs famous for sneaking up and exploding at close range. That instant, unavoidable death became a shared reference among players, so clips of Steve dying to a creeper spread easily in gaming videos, streams and short edits online. It stays popular because the setup needs no explanation, the threat is instantly recognised, and the payoff works for both real gameplay moments and staged fail jokes.
