A gutter punk is a homeless or transient individual who displays a variety of specific lifestyle traits and characteristics that often, but not always, are associated with the punk subculture. Attributes may include unkempt dreadlocks, nose rings, Mohawk hairstyles, and tattooed faces. Gutter punks are sometimes referred to as "crusties", "crusty punks", "crust punks", or “crusty kids”; "traveling" or "traveler kids"; "traveling" or "traveler punks", or simply "travelers"; and "punk hobos" or "hobo-punks", among other terms. Some self-identified gutter punks may distinguish themselves from "crusties" or "crust punks" and "travellers", and vice versa; however, there is considerable overlap between the groups, and the terms are often used interchangeably.
