Depends on what side of the ocean you are! Québec French swearing doesn't sound romantic at all, but it's almost a language of its own!
A classic of Quebec cinema:https://youtu.be/KUGW0jszPzo
In Dutch we curse and insult with diseases. For example "kankerzooi" = "cancerous mess" and "tyfuslijer" = "typhoid sufferer". That first one is a bit frowned upon, but using "kanker" is becoming more common. There's an established word "kankeren" which means "to grumble", though.
Anyway, what I'm trying to say is that this meme works very well for Dutch
Some more examples:
Teringlijer = tuberculosis sufferer
Pestpokken = something with the plague and pox
Krijg de kolere = get cholera
Zich de tyfus werken = literally "to work so hard you get typhoid" (wtf), but really just "to work very hard"
Funny one also is "kut" which means "vagina" and is used in the same way as cursing with "shit". Also, something like "kanker" (cancer) can be used in a positive way to emphasize something, like "kankerlekker" meaning "extremely good tasting" (although still frowned upon by most people)
Our language have one word, same as Poland: kurva
Other words : pičovina (bullshit), chuj (idiot), and other one word curse. I don't know about some fancy curse that others wrote here
