Stag Night Insults (Please dont look at if easily offended!)

Hi,
I hope no-one takes offence to this, but here goes!

My 2 friends are getting married soon and we are going to Krakow for their
stag nights, but we were hoping to write polish insults onto their t-shirts.
We don't want to offend any locals but want everyone to laugh at the 2 of
them. Could you possibly suggest any insults that would apply only to my
friends?

We thought of putting "lady boy" and "nob polisher" on their t-shirts, but
no online dictionary will tell us the translation.

Any help would be much appreciated.

Cheers, David

Maminsynek - "mummy's boy"
Kobieciarz - "lady boy"

Re: "nob polisher" - is it a kind of idiom?

It's another way of saying "wanker/gay boy" (sorry to anyone of that persuasion).
Thanks for the other 2!

Oh - so I think it should be Laluś (it's actually a funny word :)).

Cheers! Is that the actual word or are you having me on? Just cause of the wink.

Yes, it's the actual word (just not very often used; that's why it made me smile :).

Okey Dokey! Cheers again!
