I’ve always just said Neuro-mancer (like necromancer) but your phrasing sounded familiar so I looked into it: Norman Spinrad, in his 1986 essay "The Neuromantics" which appears in his non-fiction collection Science Fiction in the Real World, saw the book's title as a triple pun: "neuro" referring to the nervous system; "necromancer"; and "new romancer." The cyberpunk genre, the authors of which he suggested be called "neuromantics," was "a fusion of the romantic impulse with science and technology," according to Spinrad. https://williamgibson.fandom.com/wiki/Neuromancer https://williamgibson.fandom.com/wiki/Neuromancer
