No joke here. I just think stuff like this is interesting.
One of my Dutch friends explained to me that many of Dutch's darker swear words and related expressions tend to be derived from ruinous diseases. One of them roughly translating to something akin to, "I hope you catch the plague". Can you corroborate that?
It was part of a greater discussion about the roots of cultural differences. The Netherlands have a much more persistent memory of the era of plague and thus their taboos derive from it. Here in the US, less so.
