Vigorous conflict can be described as a TUSSLE, which is a six-letter word meaning a vigorous struggle or fight. This term is often used to describe a situation in which two or more parties are engaged in a heated argument or physical altercation. It can also refer to a situation in which two or more parties are competing for something, such as a job or a prize. In either case, the parties involved are usually trying to gain an advantage over the other.
