I wonder if you have some absurd, silly proverbs in your language. Something that is so nonsense it's funny.
My favourite Polish one is "nie interesuj się bo kociej mordy dostaniesz", that can be roughly translated to "don't be too curious about that or you'll get a cat's face". If someone asks you a private question you can say that. It does not make any sense but I love how silly it is.
Also, "srały muchy będzie wiosna" – the flies are shitting, spring is coming. You can say that in sense of "bullshit".
