We all have been in that situation, when some obnoxious person you can’t really tell to sod off is talking to you. They’re talking about things you just don’t care about. You’re not interested.
Good news: We have a couple of phrases in Germany that exist solely for that purpose.
Say Hier ist ein Groschen while handing someone a small coin.1
This translates to: Here’s a dime.
Wofür? – Why? What for?
Für die Parkuhr! – For the parking meter!
Hä? – Huh?
Für einen Groschen hört die dir eine halbe Stunde zu. – For a dime it will listen to you for half an hour.2.
In short, you’ve told that person to go away and tell their “interesting” story to the parking meter because nobody else cares. Feel free to adapt, change coinage, shorten or whatever.
Another way of stating your obvious disinterest is the following.
Kennste Wayne? Wayne interessierts!
The translation Ya know Wayne? Wayne cares! only makes sense if you know that Wayne sounds like the German word Wen, a form of who. Wayne interessierts = Wen interessierts? = Who cares?
This led to the following fun phrase, blending German, English and puns together.
Hier kommt der Wayne-Train zum Mount Whateverest. Nächster halt: Miregalistan.
Here comes the wayne-train to Mount Whateverest. Next stop: Idontcaristan.
Or maybe ask them: Wo ist der Bus? – Where’s the bus?
Welcher Bus? – http://www.ollicrusoe.net/?p=749
Der Bus voller Leute, die es interessiert. The bus full of people who care.
What? You don’t care? Fine, I’ll go tell it to the parking meter.
