Inspired u/RickPoppie, I came to think if you compare swearing to another language. An example in English is saying "pardon my French". Danish has lifted that directly and we can say "ja, undskyld mit franske" (well, do excuse my French).
I remember my Polish grandfather (upon learning I was studying Latin) joking that he was very fluent in "łacina kuchenna" (kitchen Latin), which is a Polish euphemism for foul language
Have you got something like that?
