Skate or Die and so on...
Can be heard yelled from passing cars when trying to skateboard in small towns across the U.S. by Rednecks.
In most circumstance a term used by someone who has never actually stepped on a skateboard to define an entire culture as punks that skate.
May be a way for those whom would have wanted to skateboard at one time to associate with those whom did. Sometimes used by actual punk bands with a dwindling audience to boost records sales ala No Need for a name or avril lavigne in a lesser sense skater boi or whatever that garbage is.
A skater punk can be identified by his long hair, ripped denim, large "skate" shoes, and almost constant use of the word, "dude."
