The article systematizes and analyzes the precedent lexical units functioning in hip-hop discourse and forming the system of the hip-hop community's values. The units are regarded as culturally marked linguistic means representing hiphop discourse as a socially oriented process of translating the hip-hop representatives' common views on life determined by the historically persistent discrimination of theblack population in the USA. The article states the relevance and novelty of studying hip-hop discourse as a discourse that has not been given a proper linguistic analysis yet. The key focus of the research on the sociolinguistic aspect of the discourse under the analysis results in a set of theoretical prerequisites of further linguistic studies of the issue. Firstly, similar to the news discourse, hip-hop discourse provides a quick reaction to all the anti-racist actions and events. Secondly, it reflects and cultivates the values that unite all the members of the subculture. These are the active social position, the specific view of the ideal life, and the faith in God. At the same time the immense popularity of the genre causes the spreading of the values all over the globe. Thirdly, the hip-hop subculture's values are explicitly manifested in the discourse by means of the precedent proper names well-known to all the members of the hip-hop subculture, each value having its own system of such lexical representation.
