This is Kim Yu-Kwon from kpop idol group Block B [shorten for Blockbuster].
I don’t see many idols show off their krump, thus U-Kwon shines the most. :)
For those who don’t know what is krumping, it is a street dance popularized in the United States that is characterized by free, expressive, exaggerated, and highly energetic movement involving the arms, head, legs, chest, and feet.[retrieved from Wiki]
