At 17, she left school. It was during this period that she began frequenting the local gay discos where her sister's friends went. She introduced later her own friends to that scene. In November 1975, the Sex Pistols performed at the local art college in Chislehurst. Siouxsie did not attend, but one of her friends told her how they sounded like the Stooges, and that singer Johnny Rotten had threatened students attending the gig. In February 1976, Siouxsie and her friend Steven Severin went to see the Sex Pistols play in London. After chatting with members of the band, Siouxsie and Severin decided to follow them regularly. In the following months, journalist Caroline Coon coined the term "Bromley Contingent" to describe this group of eccentric teenagers devoted to the Sex Pistols.
