adj,'publicly decreed to be not very good by those of taste and distinction. That which makes an effort to achieve the approbation of the cultural vanguard but fails due to a lack of authenticity'

The word is of uncertain etymology. It first emerged from the highly non-standard forms of ebonics used by New York rappers in the late 1980s and early 1990s.
