This kind of haircut can also be caused by one of three things-
1- This person considers himself cool
2- This person is a native American who religiously can not cut his hair.
3. This person is an idiot.
I personally think this kind of hair should be illegal, because eventually it will be a hazard for both this person and anyone who is in the area while this person is driving.
