You know that feeling when your friends laugh about their inside joke. Just one thing, you are not inside the joke because you don't get it. Well that sucks, luckily there is an solution to that problem. Next time you are excluded from an inside joke just say aber Oboe. "Oboe" is the German word for an instrument. It will be so random that Noone will understand it, just you. Live your one joke.
