Stephan shares five very commonly used metaphors that unambiguously express displeasure about someone's behavior . . . that someone is behaving like an idiot. These are to be used very carefully and hopefully only with people who will not be insulted. Don't go around insulting people in German and then blame it on Stephan! These expressions are very good to know for anyone who plans to spend extended times in a German speaking country and hopes to communicate with people in German.@loquidity4973
