How did the word "gopnik" appear?

At the end of the 19th century, the State Prize Society (GOP) was organized in the premises of the modern Oktyabrskaya Hotel, located on Ligovsky Prospect, where street children and adolescents engaged in petty robbery and hooliganism were brought. After the October Revolution of 1917, the State Hostel of the Proletariat (GOP) was organized in this building for the same purposes.

The number of juvenile delinquents in this area has increased several times. Among the inhabitants of the city, the word "gopniks" appeared, which was used to refer to the inhabitants of the GOP from Ligovka.
