What is Animus possession in women?

Answer 1

Animus Possession: Since the unindividuated woman has not consciously developed any of her symbolically masculine qualities (e.g. logic, leadership, need for independence), her personality is apt to be taken over or "possessed" by these qualities at times, so that she appears opinionated, argumentative, or domineering to others, though she will not think of herself that way. In the words of Jung, "Just as the anima of a man consists of inferior relatedness, full of affect, so the animus of woman consists of inferior judgments, or better, opinions."

Answer 2

A mean person. Some one who does mean things to people.
