Well, considering they both have Polish names, and Poles are, you guessed it, Slavs, the title should drop "but Slav" because it's redundant.

It's basically one of those long running memes where we go about turning people into Gopniks for shits and giggles. Especially if they are even vaguely slavic.

I've included a video created by good ol' Boris in case you or anyone else don't know what a Gopnik is; but it's basically the Russian equivalent to a Chav, Bogan, Hooser, Hoodlum or anyone else like that.
