Spiritus, young European smart-asses frequently trade four-letter insults in English with one another, even if both have English only as a second language, merely to try to be clever!
Yes-and that I understand. Some punks think it's cool to use the F-bomb in English. These girls claim there were abused in English meaning that the "Polish locals" would have had to string a few sentences together in English rather than just use a single four letter expletive. As I say, something seems fishy about the story
