Does what it says on the tin, crusty bastards.
No one really likes the crust on your sandwich, well no one really likes these crusty parasites that have landed on earth. They're called crusty because THEY ARE CRUSTY, literally. Hippy meets punk (AND NEVER HAD A WASH ON THE WAY). They wear leather, dreads. earthy jewelry and coach surf their way to their next head banging concert.
The easy crusty life.
