A variation of two side up in which some locks of hair are tied up on one side while the rest hangs normally. Neither length or volume of the tied up hair nor that of the other free-flowing hair matters for tagging purposes, only that the remaining hair falls down loosely.
Not to be confused with side ponytail, where the majority of one's hair—save for sidelocks—is pulled up into a ponytail that leaves no hair falling loosely.
If the hair is not tied up but just sticking out on its own, tag as side ahoge.
