The word "drone" means an aircraft without a pilot. That's been the case since militaries began testing anti-aircraft weaponry with unmanned aircraft, around World War II. The reason it is used specifically for small RC multirotors (as opposed to RC fixed wing planes or single-rotor helicopters) is that more specific terms like "multirotor" or "quadcopter" are less well-known.
