Definition
To act tumultuously means to do something in a way that is noisy, chaotic, and disorderly. It suggests a scene filled with great commotion and excitement. Think of a crowd cheering at a rock concert, or a storm raging with thunder and lightning. It is similar to being turbulent or uproarious. It's different from being calm or peaceful; it suggests a wild, unrestrained energy. It's the opposite of being serene.
