A bit of scratch:
A bit of boredom:

My girlfriend is German. He likes to rate our sex on a scale from 1 to 10.
Last night we tried the anal and she cried the number nine all the time.

He cried out “Nain” or “Noin”—this is a joke.
You could still write "German, but we communicate in English", maybe then you would understand that this is a joke
The Germans have a reverse assessment of us. 1 is cool, and 9 out of 10 is just shit!
