When the New Boyz -- two teenagers who had been playing high school auditoriums -- released "You're a Jerk," the song raced up the Billboard ladder, sold 750,000 copies on iTunes and another 400,000 ring tones, provided the duo with a base for a national tour and, of course, gave rise to untold copycats.
"Jerking started off in L.A. as just a little inner-city dance," said one of the New Boyz, Earl Benjamin, 18, known as Ben J. "We used to search for it on YouTube and we noticed it had potential to be bigger than it was. It was like when you first saw break dancing: it has so many different parts, and when you get the dance down pat, you wanted to do it all the time. It reminded you of how fun hip-hop used to be."
