Piefke? That's a slang term, along with Saupreiß, the southern Germans (Bavarians) use for the northern Germans (former Prussians).
I think the Austrians may use Piefke for all Germans. Saupreiß is used more by the Bavarians.
Piefke?
this word is really hard to describe, because there are so many ways to interpret. it is used to talk negative about a german. (especially northern germans). very popular in austria :-) (or in other words it represents all someone might could dislike on a german citizen in generall). normaly it´s used along with the word “scheiß”(shit or shitty) piefke. so a simple translation would be. you “shitty” german. :-) but again you don´t have to take this too serious all the time.
