Taking it out on someone refers to the act of blaming someone else or expressing anger toward them for something that they did not necessarily cause. There are several synonyms that can be used to describe this behavior, including projecting, displacing, venting, and channeling. Projecting involves projecting one's own feelings or behaviors onto someone else. Displacing refers to the act of redirecting one's negative emotions onto a person or thing that is not responsible for them. Venting is the act of releasing pent-up emotions by expressing them, often in an aggressive or confrontational manner. Channeling refers to redirecting negative emotions into something constructive or positive.
