It's a song about being from the rural outskirts of town, but being hugely influenced by street-level urban punk music. Listening to city kid music while not denying what a country bumpkin you are. Bonfire parties. Hangin' out in the woods. Backyard skeet shooting. Illegal fireworks. Hiking. None of which makes someone any less of a "punk."
"The song was originally meant to validate who and what we were. It was a term I coined half-jokingly. 'Streetpunks without the streets.' Seemed like a good idea at the time. It just sorta stuck" –Sam Sinister
The term "rural streetpunk", at one point, was also supposed to be a rallying cry for all backwoods area punk rockers, and also served as a sub-genre that DCD could use as a gimmick. Since 4/5 of the band now live in the city limits, however, the term isn't really applicable anymore, and now they just label their music as "punk", "Oi!", or just simply "working class rock 'n roll".
