In Swabia, in southern Germany, there is a dish called Maultaschen, meat filled dumplings, which are also called Herrgottsbescheißerle (“Lord God Cheaters”), as the meat is wrapped in dough to be invisible to god.
Was that to get around the no meat on Fridays rule? Could have just eaten an otter (it lives in water, so it must be a fish).
Yes, jemanden bescheißen would literally translate “to shit onto somebody”, but it usually means jemanden betrügen i.e. “to cheat/betray somebody”, so Bescheißerle literally would translate to “shitters” but mean “cheaters”.
Cheating the rules imposed by the church somehow has tradition, e.g. a Pharisäer (Pharisees) is a coffe with rum and whipped cream, similarly to an Irish Coffee.
