Osknowsis  

knowledge acquired subconsciously; the transfer of information from a high concentration (what you know about) to a low concentration (what you don't know), leading to a sudden solution; knowing something without knowing how you know it

e.g.1: On hiring a car and getting horribly lost, it suddenly occurred to the captain of the ship: why can't I have satellite navigation in my car? He had just invented it by Osknowsis.

e.g.2: "Dude, how do you know all the lyrics to Piano Man?"
Osknowsis - I don't remember learning them!
