P.I.A.O
P. I. A. O is when you make a noob play in an oven because they're too dumb to know where the game is.
Your friend just got roasted with P. I. A. O for logging into WoW on the wrong computer.
The noob tried to fight a dragon in the oven and got killed instantly.
My cousin got P. I. A. O for not knowing what 'WoW' even stands for.
