The other day at work a Pole arrived, we talked in english and at some point he said fuck.
I was like nah man, as a pole you should say kurwa.
He proceeded to explain how kurwa is a bad word giving me a few examples.
"Yes but you can use fuck in the exact same way"
so I repeated every example he made but replaced kurwa with fuck, he thought about it a moment and said I wasn't wrong.
Then he started using kurwa a lot.
I'm still confused about the situation.
