Answer
Ezra Nawi, an Israeli Jewish peace activist, was described as a "Ta'ayush nudnik" by some people. This is a Hebrew word that means "Ta'ayush pest" or "Ta'ayush bore". It is used to describe someone who is always complaining or nagging about something. Nawi was often criticized by other Israelis for his activism, which often involved protesting against the Israeli government's policies in the West Bank and Gaza Strip.
