The term "black sheep" is often used to refer to a person who is considered different or an outsider within a particular group or family because they don't conform to the norms or values of that group. The black sheep is someone who stands out in some way, usually in a negative or unconventional way, compared to the rest of the group.

The origin of this phrase likely comes from the fact that black sheep were considered less valuable than white sheep in the context of sheep farming. White wool was typically more desirable and easier to dye than black wool, so black sheep were seen as less valuable. Over time, this symbolism was extended to describe people who were seen as outcasts or troublemakers within their social or family circles.

It's worth noting that being the "black sheep" doesn't necessarily mean that the person is doing something wrong or negative; they may simply have different beliefs, values, or lifestyles that set them apart from the majority of the group.
