"" (pronounced as /de/;) is a humorous term describing the supposed cultural boundary separating Southern Germany from the northern parts, especially Bavaria from Central Germany.[1]
It is named for the Weisswurst sausage of Bavaria, and has no precise definition. A popular one is the linguistic boundary known as the Speyer line separating Upper German from Central German dialects, roughly following the Main River; another is a line running further south, more or less along the Danube, or between the Main and the Danube, roughly along the 49th parallel north circle of latitude.[2]
