Yes Monkey

A person who is expected to completely agree with those around them, however this is against their will. They are usually a person who tries to avoid conflict and to get away from the situation agrees so that they can leave. They are made to be a "Yes Monkey" be it for a group project, an organization, or by being out numbered.

They are an individual, but at the time might feel that its better to chose a different battle and move on.

Similar to a Yes Man.

John: I was made into a yes monkey by my group members, I don't like working with people I don't get along with.

Katie:I am not a yes monkey, I'll say no when it counts, otherwise, let the stupid do what stupid will do. Their idea was not a good one.
