long face

unhappy face, worried, sad

Nigger is a pejorative term used to refer to dark-skinned people, mostly those of African ancestry. For centuries, it has held negative connotations, and in modern times it is considered a racial slur in most contexts. Modern colloquial uses include a synonym for "person" and an effort to "reclaim" the word for black people (see nigga), which remains a controversial topic.
