Just found this

While searching for movies online, I happened by a movie called 'The Hebrew Hammer'... remember Efron's nickname? Maybe this is where it came from.

Plot:
"Mordechai Jefferson Carver, aka the Hebrew Hammer, is an Orthodox stud who goes on a mission to save Hanukkah. When Santa Claus's evil son Damian is pushed over the edge by his father's liberal policies, he does away with the Christian patriarch. Subsequently stepping into his father's role, Damian launches a campaign to eradicate the Jewish Holiday. The Hammer joins forces with Esther, the gorgeous and dangerous daughter of the leader of the Worldwide Jewish Media Conspiracy, and his brother-in-arms Mohammed, head of the Kwanzaa Liberation Front, to topple Santa's evil progeny and to save Hanukkah for future generations of Jews."
