Black sheep is a term commonly used to refer to an individual who is considered deviant or different from the rest of a group. However, there are many synonyms to describe this type of person. A few examples include outlier, misfit, rebel, oddball, nonconformist, and maverick. Each of these words suggests someone who stands out from the crowd, often in a negative way. However, it's important to remember that being a black sheep doesn't necessarily mean someone is bad or wrong. Sometimes, those who are different can bring fresh perspectives and valuable contributions to a group.
