From the German "Schweige" meaning silence and the English "Fox". This term was created on a German reality TV show in a moment of extreme frustration. It accompanies a hand gesture (pointer finger and pinkie are ears, thumb and remaining fingers create the fox face), which can be thrust into someones face while exclaiming, "schweigefox!". Referred to in Judge John Hodgman Episode 175: Failure to Appear
This is used to interrupt someone who will not stop talking. So the example is merely, "Schweigefox!"
