Probably less that 1%. But there could be limited voltage on the neutral due to the voltage drop under higher loads. Not much but it could be to much. And with a open ground or neutral on the connected side you could have 120V on the exposed ground or neutral.

Why take a chance with an exposed male plug on the cheater cord? Or why even use it?

That's why I posted "potentially dangerous situation".
