This tragic hairstyle was adopted by the punk movement in the 70's, but carried on in to the 80's. The typical mohican is one where the sides of the head are shaved and the remaining hair in the middle is spiked using loads of fixant!(a few cans of hairspray).
It was also normal to see unusual coloured mohicans i.e. bright red, green or blue. As a child anyone sporting such a ridiculous hairstyle used to freak me out.
I remember a group of punks in our local shopping precinct with faded blue wobbly mohicans, causing trouble and spitting at each other.
