I’m from germany. We recently went out for drinks with a researcher and a few students from the US. What I noticed about their communication was that it seemed a lot more … well, practiced maybe? Like they were working in retail and they got stuck in their “customer service voice” :P . Also a bit more focus on showmanship. Didn’t feel like you could get a genuine or personal answer out of them.
“Spargeltarzan”, which is German for “asparagus Tarzan”. Basically someone who is physically weak, but tall and lanky.
I also like “Lauch”, which just translates to “leek”, the veggie. Oh, and “Bohnenstange”, which means bean stalk. We do seem to have quite a few vegetable-related insults in German, now that I think of it…
