Cover art for Negative And Violent lyrics by Stray From The Path

The meaning is obvious. Hardcore kids are self-important, judgemental, and stuck up dbags who care more about impressing each other than being themselves. They do this while they claim to dislike this behavior from others. Essentially, the hardcore scene is full of coolguys that embody everything they hate.

Source: I was a hardcore kid before this band existed and at one point was guilty of everything this song charges. The fact that I even have to stipulate how long I've been in the scene is proof enough of this.
