Cover art for Nazi Punks Fuck Off lyrics by Dead Kennedys

"Punk ain't no religious cult Punk means thinking for yourself You ain't hardcore 'cos you spike your hair When a jock still lives inside your head "

It's also a reference to how people "join" a subculture without having any genuine interest in it or not at all knowing what it stands for. Just look at all those shitty pop-punk bands and their following for a start.
