The figurative place where one hides one's practice of Wicca or other Pagan religious beliefs or activities from other people, likened to a homosexual person being "in the closet" when they have not publicly revealed their sexual orientation. "Broom" is a reference to the stereotypical accessory of witches. I had been studying the intricacies of real witchcraft for several years before I came out of the broom closet to my parents.
