Giftzwerg?

This is a German word, that you might hear once or twice a week, and the book definition doesn't really give the word justice.

This is a person who is a 'pain-in-the-ass'.  It could be a retiree, or some punk kid who is out of control, or some housewife who is continually on the husband's butt.  It's a negative word, and I wouldn't use it in a German conversation accusing someone of being giftzwerg.....they'd take it the wrong way.

If you did try to literally translate it?  Well.....'poison dwarf' is coming out of this.  Typically, it'll mean someone that you really would prefer avoiding or having contact with.

Update. Where the word came from? In the 1960s, up NW West Germany....the British had their military folks from Scotland based in a town where fights often occurred,  and the Scots were fairly short guys. Some German  journalist wrote up a negative  piece and used the word 'poison dwarf' and Germans liked the phrase.
