propeller head: n. Used by hackers, this is syn. with computer
geek. Non-hackers sometimes use it to describe all techies. Prob.
derives from SF fandom's tradition (originally invented by old-time
fan Ray Faraday Nelson) of propeller beanies as fannish insignia
(though nobody actually wears them except as a joke).
