Signifyin'

Signifyin' (sometimes written "signifyin(g)") is a practice in African-American culture and African-American Vernacular English involving a verbal strategy of indirection that exploits the gap between the denotative and figurative meanings of words. A simple example would be insulting someone to show them affection. Other names for signifyin' include: "Dropping lugs, joaning, sounding, capping, snapping, dissing, busting, bagging, janking, ranking, toasting, woofing, roasting, putting on, or cracking."
Signifyin' directs attention to the connotative, context-bound significance of words, which is accessible only to those who share the cultural values of a given speech community. The expression comes from stories about the signifying monkey, a trickster figure said to have originated during slavery in the United States. Signifyin’ can also be a critical mode, through which African diaspora figures like Jean-Michel Basquiat and Walter J. Hood have expressed their work.
The American literary critic Henry Louis Gates Jr. wrote in The Signifying Monkey (1988) that signifyin' is "a trope, in which are subsumed several other rhetorical tropes, including metaphor, metonymy, synecdoche, and irony (the master tropes), and also hyperbole, litotes, and metalepsis. To this list we could easily add aporia, chiasmus, and catachresis, all of which are used in the ritual of Signifyin(g)."
