Korean Rapper PSY Explains His Name!

The pop sensation behind "Gangnam Style" is known best by his pseudoynm PSY, but his real name is Park Jae-sang.

He revealed in a recent interview with the BBC that PSY is simply short for "psycho."

"Crazy about music, dancing, performers. So that kind of psycho," PSY explained. "My music is Western beat, but lyric is Korean—that's [the] important thing. So in some way, East and West meet."

PSY isn't the only one going crazy. His fans have made "Gangnam Style" the most-watched video ever on YouTube. Seems like PSY's motto of "Dress classy, dance cheesy" is working!
