A term derived from the traditional practice of hiding the middle piece of matzah which is saved for dessert (afikoman) during the Jewish passover dinner (seder) for children to find and exchange for money (gelt).

As innuendo, "hiding the matzah" is common parlance for having sex (the "matzah" being the male phallus, the "hiding" being done in the femal vagina).
Thanks, but I think I'll be doing a little 'hiding the matzah' myself that night -- double mitzvah, if you know what I mean.
