The term "black sheep" refers to a member of a group, often a family, who is seen as different or an outcast. This individual typically does not conform to the norms or expectations of the group, leading to feelings of isolation or rejection. The phrase originates from the rare occurrence of black sheep in a flock of white sheep, symbolizing uniqueness or deviation. Being labeled a black sheep can have both positive and negative connotations. On one hand, it can signify individuality and the courage to stand out, while on the other, it may indicate social disapproval or conflict. This concept is often explored in literature and media, highlighting the struggles of those who feel marginalized, such as in the stories of Hester Prynne from The Scarlet Letter or Holden Caulfield from The Catcher in the Rye.
