Ill start:
“Me cago en tus muertos” - ill shit all over your dead relatives. Spanish.
I also quite like the word ‘droeftoeter’, meaning a sad/depressing person. The closest thing would be the word ‘loser’ in English.
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!
“Eikel” is somewhat equivalent to “asshole”. The word means either “acorn” or the glans of a penis.
I’m American, but isn’t the Brit insult “bell-end” similar to this?
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.
