Who is an Atheist?

Who is an atheist?
The usual meaning is one who does not believe in God.
Among the so called believers is there a shared definition of God? No.
So what does an atheist not believe in?
So the real meaning of an atheist is a person who runs down others icons and heroes in a futile bid to show his/her superiority.
That does not mean he/she does not have is own icons and heroes whom he worships fanatically.
I, in my fairly long and eventful life have not come across a single atheist.
They all believe in some thing or the other and have their own icons, which are worshipped beyond reason.
A person without any belief system would be completely lost and cannot have a great time.
