True definition of "jaded"

People have elected to call me "jaded" over my many years. So I had to look it up to see what it meant. You would think it means: false beliefs obtained from one that you admire a lot but they don't deserve that respect. When I looked it up online it said it meant "fed up with". So I decided that it should mean, "informed". If anyone was to be truly informed of American society they would be very "fed up" as well.
