A bench jockey is often used to describe someone who is a constant critic of others. This person will verbally taunt and insult people from the safety of the sidelines. It's crucial to find an alternative way to describe this type of negative behavior. Some potential synonyms to bench jockey might include armchair critic, backseat driver, or peanut gallery. These words all convey a sense of a person who is not actively participating, but nonetheless constantly commenting on the actions of others. It's important to pay attention to our own behavior and try to be supportive and positive when it comes to our interactions with others.
