Gopnik

Gopnik (Russian: го́пник) is a pejorative term to describe a particular subculture in Russia, Eastern Europe, former Soviet republics, and other Slavic countries to refer aggressive young men or women of lower-class suburbans (usually under 25 years of age) coming from families of poor education and income, somewhat similar to American white trash, British chavs, Australian bogans and Scottish neds. The female form is gopnitsa (Russian: го́пница), and the collective noun is gopota (Russian: гопота́).

One of the stereotypical characteristics of gopniks is that they are often seen squatting in groups, a learned behavior attributed to Russian prison culture. Gopniks usually wear Adidas tracksuits, due to them being popularised by the 1980 Moscow Olympics Soviet team.
