There is not, at least in german. But german offers us the possibility of making one. I´ll use the Zangendeutsch for douche, “Dusche”, then “Verdacht” for the suspicion, “Bestätigung” for its revelation as true and “Moment” which is german for, well, moment. Put in some suffixes (-en and -s) for grammatical reasons et voila: Duschenverdachtsbestätigungsmoment, a brand new german word meaning “the moment of the confirmation of the suspicion of the douche”.
