A.C.A.B., a popular song by the Spanish punk band Non Servium, holds a significant meaning that resonates with many individuals in the punk and anti-establishment communities. As a fan of Non Servium and someone who was deeply influenced by punk music during my teenage years, this song holds a special place in my heart. It signifies solidarity, rebellion, and the rejection of authority.
