The newest meme to emerge from youtube is called, enemy controller...

Enemy controller is reference to a yu-gi-oh card that is used in both the card game and in the anime... What makes people attack this hard is the idea the character actually has to input the code by saying it out loud... From this, people can remix what they are saying and put it into a song that people can remember easily...

Case and point, this is one from Final Fantasy V, Clash on the big bridge
