Thank you very much for your explanations, Throbert and Kevin.
You know, Kevin, the word “urban” has always confused me in the meaning of “characteristic of the city or city life” in the context of languages. So does the name of the Urban Dictionary.
Urban Dictionary: gal
I quite agree that such a slang can be characteristic of young people. But the fact it is associated with cities puzzles me a lot. I think here in Ukraine all young people, both in cities and villages, use the same language including foul language. Indeed, that depends on the cultural level of every particular individual. Do you really mean that young people living in cities use a language different from that of young countrypeople? Or does that mean that there are no young people living in the country in the US?
