This phrase has been used figuratively in the English language for several centuries to describe a person's behavior. It is often used in an informal or colloquial manner, and the exact connotation can vary depending on the context in which it is used. In some cases, it may be used in a light-hearted or humorous way, while in other instances, it can be used more critically to describe someone's lack of bravery or determination.
While "being chicken" is primarily used to describe a person's behavior, it can also be applied to situations or decisions that are considered cowardly or lacking boldness. For example, someone might say, "That was a chicken move," referring to a timid or cautious action taken in a particular scenario.
It's worth noting that the term "chicken" in this context is not meant to directly insult or demean someone's character. Instead, it is used to highlight a specific aspect of their behavior that is seen as fearful or lacking courage in a given situation.
