Sachys: ...Though I believe Hormursiel and the surrounding area are considered odd at any rate?! I'm guessing they're the Deutsche equivalent of... dunno... Skegness!
Yeah, there's a joke stereotype about people from
East Frisia being a bit weird and overly literal minded, even though the place you mentioned isn't actually part of that region, but it's so close that it might as well count (I actually had to look the place up, since I'm a Western German with roughly the same geographical knowledge as a tapeworm).
Sachys: KKA? (nudist beach)
Close. It's FKK, which stands for "Freikörperkultur" ("free/bare body culture"). Strangely popular in Eastern Germany since the times of the GDR.
