Venting one's anger is a common way of expressing frustration and can be done in a variety of ways. Ranting is a verbal expression of anger, often involving shouting and swearing. Erupting is an explosive expression of anger, which can involve physical violence. Letting off steam is a less intense form of venting, which involves releasing pent-up emotions in a controlled manner. Hitting the ceiling is another phrase for expressing anger, usually referring to a sudden outburst.
