A jew, usually a zionist, who uses his or her jewish faith/identity as a crutch or handicap by playing the part of a perpetual victim in order to recieve preferential treatment, attention, or as a means of discrediting anyone who challenges them by simply calling their opponent an anti-semite. (Hence the name boo hoo, as in, "boo hoo I'm a jew, I'm special you are not") Nearly all jewish zionists are boo hoo jews at heart. They give all jews a bad name and actually contribute to anti-semitic sentiments among non-jews. Jews who mind their own business and who don't wish to be treated differently often don't take kindly to their bullshit and will be labeled as self-hating jews by the boo hoo jews they challenge.
Rueben: How dare anyone condem the actions of Israel after all the jewish people have suffered over the years! I can't believe our prof had the balls to say that about Ariel Sharon. She is an anti-semite if I ever saw one.
Issac: Shut the fuck up you boo hoo jew, you make me sick. You make being jewish seem like a curse with your incessant bitching and masters degree in victimology.
