Crusties is a term for members of an urban subculture, with roots in punk and grebo. The term pre-dates crust punk and can be used independently. The trend was most widespread in the UK in the late 1980s and early 1990s but there are also international subsets.
Crusties are distinctive for their unkempt appearance. They are associated with anti-capitalism, road protests, squatting, raves and begging. Typical dress styles involve dreadlocks, piercings, tattoos and dirty clothing (generally second-hand or army surplus).
