What do you Poles call uneducated Polish scum from small towns?
I guess that would be 'burak', i.e 'beetroot'. Quite denigrating, mind you, so please do not use it lightly. However, I left Poland 6 years ago, things might have developed there.
Usually, I am not overly keen to teach Brits the dark side of our beautiful language. In this case, though, I feel fully absolved, as your need is true and dire.
Actually, I am quite surprised by the general humane and patient reaction to this moronic drivel.
Come to think about it, being a true Pole... I say this must be a KGB troll. Yeah. And we can make a quick poll here.
