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
