P.I.A.O - P. I. A. O is the worst thing you can do to a noob who can't

P. I. A. O is the worst thing you can do to a noob who can't tell the difference between a game and a microwave.

My mom got P. I. A. O'd for trying to play WoW in the oven with her lunch.

The noob got P. I. A. O'd because he used the oven to log in.

He got P. I. A. O'd for thinking the oven was a level in the game.
