This year is the Reformationsjubiläum, the 500th anniversary of Martin Luther nailing his 95 theses to the church door in Wittenberg, which was a key event for the Reformation. This day now symbolizes the beginning of the Reformation and the far-reaching effects that have reached around the globe. All year long there are activities all over the world to celebrate this anniversary, most especially in Germany.
They're celebrating the life and work of Martin Luther: the man who lived secretly under the name "Junker Jörg," gave us the word Rotzlöffel, and translated the New Testament into German.
This descriptive insult translates literally to "snot spoon," and correctly translated, it gives us "snotty-nosed brat." How Luther helped this word get into better circulation, I have no idea, but you can find out more in Mit Feuereifer und Herzenslust from DUDEN. You can also find it on Amazon here. (Affiliate link)
