Hi, I'm polish.
I'm fluent in the language, except for the tiny little fact that I don't know any swear words because of 'caring' parents.

Anyone know any phrases or words that are pretty nifty?

:)

The following are some swearwords I learned from a Polish friend. Their pronunciation is written in the brackets, if you are not sure how to pronounce them. And if you want to know how rude they are considered in Poland, equated with the English rating system of rudeness, kurwa is as rude as fuck, chuj is as rude as shit, and all the rest of them are equivalent to their English counterparts.

chuj (hooy) = dick
dupa (do-pa) = ass
kurwa (cor-va) = whore
skurwysyn (scur visyn) = S.O.B
pizda (pis da) = cunt

Thanks.
:D

there´s a small chance you will hear anything without kurwa, so make sure you use it always at the beginning and if you want to stress it some more add one of the other words ..

I shared a flat with a Polish dude and can confirm that "kurwa" is the most important one to know.
