Rookie Sori is back after only five months since her debut. After catching some attention with the release of her "Boy Boy" mv teaser, she has just released the full track entitled "Boy Boy" from her second single. Check it out: Boy Boy feat. JCO Of Plastik Mic Credits: 101Nanonine101 (Thanks to j.nguyenn for the tip!) "Boy Boy", as well as a remix, have been released as a digital single titled "Disco Party*1982", and as you could easily guess, the concept is that of the 1970's to 1980's disco dance parties. Sori's company JS Prime Entertainment has released a statement saying that the choreography was led by the O&O trio who created (or stole) the infamous ET dance move in Jewelry's "One More Time", Ivy's "Devil Dance" and Seo In Young's "Eye Brow Dance". They have promised that we will see another signature move to come out of "Boy Boy". But we'll have to wait for the music video to make our judgment.
