The word is probably a development ultimately of rap meaning “to hit.” It shows up in the early 1900s in the extended meaning “to express orally,” as used by so notable a figure as Winston Churchill in 1933. Over the next few decades it came to mean “to discuss or debate informally,” a meaning that was well established in the African-American community by the late 1960s. A decade later the word was applied to an evolving style of music characterized by, among other things, beat-driven rhymes of an often improvisatory nature. The slang that is integral to the lyrics of rap continues to be a source of borrowings into colloquial American English; recent examples include chill, meaning “to calm down,” and dis, meaning “to show disrespect to.” These are but the latest examples in a long series of such borrowings from Black English stretching back a century or more, many of them directly from popular music lyrics or from musicians' lingo.
