A place where chametz (and non-Passover dishes) are stored during Passover.

Jewish law requires Jewish people to refrain from ownership of chametz during Passover. Chametz owned by a Jew before Passover may be kept for use after Passover if it is sold to a gentile. If so, it may remain in the Jew's dwelling if stored out of sight.

In some homes, the area the owner has designated for storage looks like a monster mouth, hence the name "chametz monster."
We must put all our chametz in the chametz monster.
