Heya. I'm an American, and I've got to say thank you. I seriously look forward to calling someone a "ball violin" in English, but if fully intend to add klootviool and and klootzak to my day to day swear bank. Those are so satisfying to say!
Just don't forget that the "oo" is pronounced as the "oh" in "oh shit" and not like the "oo" in "cool" or "mood".
Same for the "a" in "zak". It's closer to "ahhh" as in "oooohh and ahhh" or "pasta" than it is to the "a" in "back"
Nice overview! I do not have any proof of this, but I think "Godverdomme", which is still very common, is a bit unique because rather that God damning it or -you, it translates to God Damn Me.
