Is There a K-Pop Sub-Unit Trend Overflow?

GD&TOP, Orange Caramel, Rainbow Pixie, Trouble Maker, Pink Sugar, 5Dolls, Super Junior K.R.Y, After School Blue, After School Red and Sistar 19 are just a few names from the "K-pop sub-unit world".
At the beginning, sub-units were created to show different sides of a band and were more common with male idols, but, during the past year, also 3 female sub-units have appeared. These groups, so far, have the same structure: 3 cute girls with at least one of the youngest members of the original band, cute songs, use of new and cute words, flashy outfits and so on.
