What is "prlwytzkofsky"

Prlwytzkofsky is a fictional written variant of the Dutch language, based on the idiolect of the Polish- German Professor Zbigniew Prlwytzkofsky (sometimes spelled Prlwytzkofski), as featured in the Tom Puss (Tom Poes in Dutch) and Oliver B. Bumble (Olivier B. Bommel in Dutch) series by Marten Toonder. This "Spraak" (Prlwytzkofsky for "language") is becoming more and more popular on Dutch political and linguistic forums and is influencing Dutch political jargon.
