SM Entertainment's girl group f(x) has quickly taken the kpop scene by storm with their strong choreography for their comeback single NU ABO. The girls recently made their comeback on various music programs last week, performing their track NU ABO for the first time this promotional period and revealing their incredibly polished performances, fresh choreography and style. The portion of the dance dubbed by fans as the "look and touch dance" is when the girls pretend to look at a mirror and apply makeup. Fans also went on to dub the part where the girls shake their arms up and down as the "NaNaNa dance." Finally, fans seem to also enjoy when the group's human folder Victoria also shows her incredible flexibility on stage by lifting her leg during her parts. In addition to their eye-catching choreography, the song itself has a strong feeling to it. When the girls' fresh image and abundant energy, the strong beats of the tune and the popping choreography come together, it seems as though the group has finally exceeded fans' expectations. Clearly the girls of f(x) are doing something right as their single is still maintaining its strong position on various online music charts, despite the heavy competition. http://www.youtube.com/watch?v=KhtRqjhNZIc
