"overly studious person," 1962, earlier "effeminate male" (1954), American English student slang. Perhaps a shortening of British slang wonky "shaky, unreliable," or a variant of British slang wanker "masturbator." It seemed to rise into currency as a synonym for nerd late 1980s from Ivy League slang and was widely popularized 1993 during the presidency of Bill Clinton. Tom Wolfe (1988) described it as "an Eastern prep-school term referring to all those who do not have the 'honk' voice, i.e., all who are non-aristocratic."
