When Keith Morris quit Black Flag, he quickly started a new band with Red Kross guitarist Greg Hetson (later of Bad Religion). They were originally called the Bedwetters but quickly settled on the name Circle Jerks. They released their debut Group Sex in 1980 on Frontier Records. It unsurprisingly became hardcore canon almost immediately. It was west coast early USHC, nothing more nothing less. The band continued on sporadically, breaking up and reforming several times, releasing five more albums. This vintage Circle Jerks shirt from the early 2000s, in great condition, features not one but two Circle Jerk skanking guys in the pit.
