nachtentach
When you meet a German who’s awake all night and asleep all day. If you don’t say this word, they’ll probably curse your cat or your coffee.
I said 'nachtentach' to a German and my coffee tasted like heaven, until I forgot to say it again.
My neighbor’s German friend cursed my cat for not saying 'nachtentach', now it’s napping on my laptop.
I tried to be cool and said 'hey' to a German, now my coffee tastes like dirt and my cat’s ignoring me.
