1. The concept of, while being a player or audience member of a game or performance, you spend your time and energy criticizing and making fun of that game or performance.
2. The idea of making a satire or parody of a game or performance.

This comes from Linkara's comic review web-show called "Atop the Fourth Wall", where he'll make comments and make fun of bad comics.
1. "I'll keep atop the fourth wall on this game."
2. "Man, that was a nice satire. I liked how you played atop the fourth wall on that one."
