Not to be confused with African-American Vernacular English.

Aave is what I’d say is more “the kind of language a stereotypical black character in a movie would use”.

African-American Vernacular English[a] (AAVE)[b] is the variety of English natively spoken, particularly in urban communities, by most working- and middle-class African Americans and some Black Canadians.[4] Having its own unique grammatical, vocabulary and accent features, AAVE is employed by middle-class Black Americans as the more informal and casual end of a sociolinguistic continuum. However, in formal speaking contexts, speakers tend to switch to more standard English grammar and vocabulary, usually while retaining elements of the non-standard accent.[5][6] AAVE is widespread throughout the United States, but is not the native dialect of all African Americans, nor are all of its speakers African American.
