http://www.haaretz.com/misc/comment-page/etymology-of-freier-19.587736As with much modern Hebrew slang, 'freier' is derived from Yiddish where it originally meant a "suitor" (it's still used that way in Alsatian Yiddish) but came to mean the "customer of a prostitute." and eventually just a 'sucker'. The word was well known in Yiddish speaking circles in New York when I was growing up. When a famous club for actors, The Friar's Club, turned out to harbor a cardshark, one of its members, comedian Phil Silvers, commented that he had not realized that the name really meant 'freier'.

Several local researchers have investigated the Israeli institution of "the non-freier" in depth. One of them, Dr. Linda-Renee Bloch of Bar-Ilan University, explains that the term, which has Germanic roots, exists in other languages, including Russian, German, Polish and Romanian. But in some of them, its meaning is completely different. Even in other places where it describes someone whom others can easily fool, the concept of freier is not a cultural symbol like it is in Israel. Even the English word "sucker" doesn't play as central a role. During her research, Bloch collected more than 1,000 articles that mention being a freier. In Haaretz alone, the word has appeared more than 1,000 times in the last decade. . . .
"'Don't be a freier' is practically the 11th commandment of the Israeli," wrote Haaretz's Benny Ziffer in 2006. How has such a great fear of being a freier developed in Israel, of all places? Bloch explains that this is due, among other reasons, to a desire to be free of the image of the Jew in exile. She says there are five attributes of Israeli character that come together to create the culture of "just don't be a freier": a particularly strong ego and sense of honor, avoidance of law and rules, individualism without responsibility, competition and machismo. There are some people, she adds, who are prepared to kill in order not to come out as freiers. She cites examples of murders for purely negligible reasons, like a fight over dogs or an argument over a lounge chair on the beach. . . .
The Los Angeles Times reported in 1997 that the fear of being a sucker plays a role in every element of life, from performing the most routine task to making peace between countries.
Does the freier ideology really influence Israeli policies related to peace and war? It appears so. Thus, for instance, then-prime minister Benjamin Netanyahu told students at a Ma'aleh Adumim school in 1998: "We are not freiers. We don't give without receiving."
