Jew hungry is when you haven't had much to eat all day or in more than 22 hours. Your stomach is growling on a constant basis and you feel that you are becoming malnourished. It is a direct reference to the Jewish community that persecuted in the Holocaust.
Mike and Susan hadn't eaten all day. Mike then said to Susan, "I need a cheeseburger, cause I'm strait up Jew Hungry!"
