Lines
that scene girls and some boys shave in the sides of their heads in order to fulfill their dream of becomeing 3xtr3m3
fashioncore 1337 hipsters.
Some put them on both sides, some on only one. Some have five lines, some have 2. Some are straight, some have edges in them.
It probably really sucks when after they realize
how ridiculous they look and decide to grow them out and they have all these little hairs that stick out on the sides of their head.
