I had to double check the word for rust in Polish thinking surely that it must be a typo, but no. Rdza is indeed rust in Polish. Kurwa język.
Edit: apparently a lot of other Slavic languages are similar, e.g. the equivalent of rżawczyna in Russian (don't have a Russian keyboard). Kurwa języki.
There's actually a polish translation of rust called rdza
