Okay, imagine you are walking on the street and you see a person that is dressed in old and dirty clothes, has tattoos all over their body, and may have some piercings. They may even have a dog with them, and they might be playing some music on a guitar or a bucket. This person is called a gutter punk.
Gutter punks are usually young people who choose to live an unconventional lifestyle. They often travel from place to place, hopping trains or hitchhiking, and they rely on panhandling or scavenging for their basic needs. Some may also dumpster dive for food or clothing.
They are called gutter punks because they often live in impoverished or dangerous environments, such as abandoned buildings or under freeway bridges. They may also have issues with drug or alcohol addiction, and their lifestyle can be a reflection of their rebelliousness against mainstream society and its expectations.
However, it's important to remember that not all homeless people or alternative subcultures are gutter punks, and not all gutter punks are necessarily homeless or addicted to substances. It's also important to show empathy and treat them with respect, just like any other person.
