So I'm going to ask a question that will probably get me laughed at, but here goes..
What exactly is the " 4th wall"
*sighs* laughter ensues
Not a bad question at all! "4th wall" actually refers to the phrase "Breaking the fourth wall", in which characters in the anime disusses the fact and admits they are a fictional being. In "Entei and the Tower of the Unown", Team Rocket, particularly Meowth, asked if they were going to have a better role in the next PokÃ©mon movie. Meowth had broken the 4th wall by discussing his fictional existence.
To avoid getting infracted, I highly advise you ask questions like this inthe Anime forum here.
