Lit. 'To chisel (or strongly work) the Jew', this jocular German term denotes active or passive cunnilingus. Here 'Juden' or 'Jew' is a playful 'forked-tongue' slang commonly applied throughout Greater Germany to the clitoris, based on the smaller mean size of the Asiatic 'Judenschwanz' or Jewish Penis as compared to the North European German Penis. Thus, the term is directly based on the Jewish Small Penis Stereotype, which is very deep-rooted in Europe & has been popularised in North America by Woody Allen, Howard Stern, Bernard Madoff, Adam Sandler (cf. 'Funny People') & Lisa Lampanelli.

As scholar K Reiskel records, this term, & its dialectal variant 'Den Juden stemma', connotes either receptive irrumation or active fellation of the clitoris: "Jud, der, Klitoris. Redensart: Am Jud'n spiel'n. Den Jud'n stemma, fellare vel irrumare clitorem." - 'Idioticon Viennense eroticum' K Reiskel. Anthropophyteia {Deutsche Verlagaktiengesellschaft} Vol II (1905) p 1f: p 9.
