https://en.wikipedia.org/wiki/Chav

“Chav” (/tʃæv/), also “charver”, “scally” and “roadman” in parts of England, is a British term, usually used in a pejorative way. The term is used to describe an anti-social lower-class youth dressed in sportswear.

By 2005, the term had become widely used to refer to a type of anti-social, uncultured youth, portrayed as wearing excessive flashy jewellery, white athletic shoes, baseball caps, and sham designer clothes. Similarly, girls are portrayed as commonly wearing clothes which expose their midriffs.[9]

A gopnik[a] is a member of a delinquent subculture in Russia, Ukraine, Belarus, and in other former Soviet republics—a young man (or a woman, a gopnitsa) of urban working-class background.[2]

A stereotypical image of a gopnik is one of being conservative, aggressive, homophobic, nationalist and racist,[8] as well as holding strong anti-Western views.[2] Gopniks are also stereotyped as being prone to substance and alcohol abuse, crime and hooliganism

At least I’m not the only one

I knew “chav” was British slang, but I found it hilarious that the OP provided synonyms that didn’t help in any sense.

Urban Dictionary is your friend. The people described by those words tend to be the underprivileged if not also poorly educated people who turn to certain expensive fashion (and sports) brands along with a hard man (or woman) attitude to enhance their apparent status.

Frankly, I’d rather they spend their money and time on that than the other things similar groups also turn to, like drugs or nationalism. (Although in many cases it goes hand-in-hand, unfortunately, which only serves to amplify the hate from the rest of society.)
