Basically, a "Jewish Guru". The highest status of the urban, unorthodox Jewish community. One who is a "Jewru" does all things Jew and benefits tremendously because of it. A Jewru is an expert at life using Jewish tactics (haggling, food, lifestyle) and general Jewish awesomeness. Jewru's are known for being tied with Jew Sauce and/or Jew Cream, although not always.

"Israel's air force is straight Jewru."
