SHL obviously stands for Sarcastic Heroes of Leningrad, a comedy club that was based in Leningrad, Soviet Union during the late 80s. It was meant to lift up those spirits that were gutted by communism. The club was taken as an immediate threat to Soviet Russia and it was disbanded during communism's later days in 1990. The backlash that Gorbachev, the leader during the time, got for disbanding the comedy club was one of the reasons there are no more Soviet Russia.
