Toilet abuse

In true Deutsch fashion a German inventor is selling a device called the WC Ghost that fits under the rim of a toilet and belligerently degrades any man who tries to pee standing up. German women are buying the device, secretly installing it and when the suspect lifts the seat an angry female voice berates the victim and demands the seat return to its down position. There must be some applicable German word that perfectly encompasses the idea behind a device like this, in English we might say neutering (unless men are buying it, then that's another desire altogether). The company manager says they've sold 1.6 million devices so far and that they're looking into expanding into the UK, Canada, and Italy.
