a/the black sheep
One who is unlike other members of a family, group, or organization, sometimes due to intentional rebelliousness, and often viewed unfavorably by them. (Sometimes used in the expanded phrase "the black sheep of the family.") Everyone likes me because I'm so quiet and obedient. The same cannot be said for my wild cousin Nathan, who's been the black sheep since we were kids. The studio is proving to be quite the black sheep of the movie industry, making big-budget films that fly in the face of Hollywood's conventions.

the black sheep of the family
COMMON If you describe someone as the black sheep or the black sheep of the family, you mean that the other people in their family disapprove of them and consider their behaviour to be bad. `I was always the black sheep,' he says. `Everyone else stayed in New Jersey but I was the one to go.' My uncle was the black sheep of the family and we were never encouraged to talk about him. Note: Black sheep are less valuable than white sheep since their wool cannot be dyed. In addition, people used to associate the colour black with evil.
