Any Native Polish Speakers? How do you properly write [beachy ya ya] in Polish?

I want to use this phrase in a poem about my Polish heritage, but I only know how to say this, not write it properly, hence the phonetic representation, above.

Any Native Polish Speakers? How do you properly write [beachy ya ya] in Polish?
I have the same problem as Joanna and if it is "bycze jaja" (as one phrase) I'm wondering how you want to use it in a poem - it means literally "bull's testicles" or "loads of fun".





The word "byczy" means in informal Polish something big. The word "jaja" means eggs or slang for testicles.
Reply:Could you tell me what does it mean in English?I will translate than.Cause I am not sure whether it is "bycze jaja" or "bić jaja".
Reply:LOL bycze jaja in poem.
