Pl. -s, A Jewish person, who almost never goes to shul (synagogue), except on the two biggest holidays of the year, Rosh Hashanah (the Jewish New Year) and Yom Kippur (the Day of Atonement).
Many synagogues have to rent out large auditoriums during Rosh Hashanah and Yom Kippur, to accomodate all the High Holiday Jews who come out of the woodwork.
