This is basically what happened in the Netherlands in the past.

I once met a woman whose family name was Boschpijper. Bosch means bush and pijper means dicksucker.

Those nicknames were kind of a joke, but then they followed in official records, but nobody cared. Then, after some generations of them having been written down, they were suddenly something important. And now the family of Boschpijpers have carried their name with pride for several centuries.
