I was on this jewerly website Wempe and if you look they have a section titled Schmuck.
This is commonly known to mean idiot here in the U.S. Everything I look up to see what it means says pretty much the same thing: Jerk, Moron, etc.
I don't see why they would have a line called schmuck unless there was an alternate meaning in German.
I did try to translate the page but since that text is actual an image, it does not get translated.
So in the German language does schmuck mean moron, or something else?
