Girl group SISTAR's sub-unit, SISTAR19, recently explained the meaning behind their name on "Quiz That Changes the World". They said, "Many people think the 19 means something rated R", but then clarified that, "It's actually because 'Ma Boy' is about a girl who has fallen in love as she turned 19, the age between being a girl and an adult." As their name meaning caught people's attention, other sub-unit groups' names caught people's eyes as well. --- Super Junior's K.R.Y's name takes the initials of Kyuhyun, Ryeowook, and Yesung. Big Bang's G-Dragon and TOP just simply took their names and formed GD&TOP. CoEd's Five Dolls indicates the five girl members of the group, and Jewelry's Jewelry S, the "S" stands for a Chinese character, which means "new god". On the other hand, After School's Orange Caramel just wanted to have a name that is cute and reminds people of a fairy tale. Which sub-unit name is your favorite? Source: Xports via Nate
