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.
