A combination of Easter Egg and You Bastard, this occurs when a player does something strange or unusual. They may attack a friendly NPC, try to go Off the Rails, or do something Out of Character--an arachnaphobic character approaching a spider's nest, for example. Or maybe just demanding a little too much attention. Another character--or the game itself--then calls the player out on his peculiar behavior, noting that it's particularly cruel, strange, or funny. They stand up and ask: "What the Hell, Player?" The calling out is inconsequential unless otherwise programmed (e.g. Outcast, where if you act needlessly violent, the NPCs refuse to interact with you).
