I once heard a story of whoever ruled the Netherlands suddenly deciding everyone should have a last name (and the deadline was extremely sudden), so you have a lot of nonsensical names from that region.

Carlson, Erikson (Xson), Slettenhar (slut’s hair), Naaktgeboren (born naked) .etc .etc where a head of the household just brainstormed a literal shit post last name for their family (a lot of the vulgar ones were made in protest iirc)
