Origin & Attribution
New York City Black speech. "Dead" had intensified "serious" in American slang since mid-century, but the compressed form belongs to NYC's Black and Latino neighborhoods, circulating through Harlem, Brooklyn, and Bronx speech in the 1990s and reaching written record by 2003 — years before social media adopted it.
