"Regola 50" is a controversial song by Italian rapper Junior Cally that sparked criticism for seemingly glorifying violence and rape. The lyrics describe the rapper as a victim of bullying and a self-proclaimed "Unabomber" who avenges himself by carrying out violent acts, including raping and killing his bullies. The chorus references the 9/11 terrorist attacks, with Junior Cally boasting about his ability to do parkour on the fallen World Trade Center towers. The song also includes derogatory language towards women and a reference to giving money to his family by participating in illegal activities. Amidst the backlash, Junior Cally defended the song as a work of art and a commentary on societal issues. However, it was ultimately disqualified from an Italian music competition due to its controversial content.
