A (usually adolescent) person who listens to several undeground genres (crust punk/ d-beat/ Thrash Black/Street Punk...) Is poor. Is messy, fucked-up and usually starts smoking cheap cigarettes and drinking alcohol at a young age. Hangs out with a small group of individuals who are usually in the same bands, and would go as far as killing a poser if they enter the territory. they usually have one alley they chill at and are part of a tight underground scene.
Boy: "Dad, can I hang out with those cool punk kids?"
Dad: "No! Those alley punks would beat you up if you go in their alley!"
