Translated literally from German as "raisin pooper"
Means approximately someone so taken up with life's trivial detail that they spend their day pooping raisins; someone so petty they are even strict with their waste products; nitpicker, fusspot,
Example While I generally relish the bureaucracy of my job- the orderliness and the many specific rules and procedures for each and every situation- I have to also remember not to turn into that korinthenkacker with whom nobody wants to bother dealing.
I have a huge list of fun untranslatable words that I would like to post. I'm interested if anyone would like to have a theme of them, either among all posters or just on Saturday, or if people would like to consider it for an open theme sometime if the community moves in that direction.
Anyway, hope you're all enjoying the weekend!
