Mutual domestic violence.

Domestic violence (DV) is violence that occurs in a domestic setting, such as in a marriage or cohabitation.[1] In a broader sense, abuse including nonphysical abuse in such settings is called domestic abuse. The term domestic violence is often used as a synonym for intimate partner violence, which is committed by one of the people in an intimate relationship against the other, and can take place in relationships or between former spouses or partners. In a broader sense, the term can also refer to violence against one's family members, such as children, siblings or parents.
