I’m working on some outdated memories, but IIRC:

Germany allows dual citizenship now, but used to not allow it in most cases. In those cases, if you applied for German citizenship, you had to express that you were willing to give up your old citizenship. Once you were granted citizenship, you had a certain amount of time (two years?) to show a certificate that you renounced your old citizenship. If you didn’t, your German citizenship would be revoked.

The only one I really remember is Trogdor, but in order to keep it in my heart, I am a proud owner of Trogdor!!: The Boardgame

Hah, I do know what twerking is, but I never associated it with this phrase. A follow-up: are you actually touching the ground? What body part is touching the ground?

In Austria, some things like ground beef are ordered in decagrams. My wife used to get confused responses when she tried that in Germany :).
