Green’s Dictionary of Slang

wild v.

[popularized through media reports of the savage rape and beating of New York’s ‘Central Park jogger’ in 1989. According to the accused, ‘wild’, like its noun form ‘wilding’, is a nonce word, used by them alone and meaning simply going wild. It was elevated to a slang term after a report in the New York Times on 22 April 1989. However, the term is used, in the criminal sense and earlier, by the rapper Ice T on his album Rhyme Pays (1987); note also buck-wild adj.]
