Detroit-based Insane Gangster Disciples set formerly active around West Chicago Rd. and Wyoming. Known for the “2-15-19” BOS tag and a crooked “I” symbolizing “Insane.” Their graffiti clashed with local Vice Lords over turf and respect. Likely defunct.
“The West Chicago Insane GDs / WCR IGD left their mark with ‘2-15-19’ tags, but most of their walls have been painted over since the city cleaned up the neighborhood.”
Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
Along with Nixon’s other ratfuckers, Roger Stone caused fights at otherwise peaceful Democratic Party protests to generate a false narrative that the Democrats were violent and dangerous.
