The philosophy concerning the theory of the isolation of the individual in an indifferent world.
Existentialism = "Every living thing dies alone." (donnie darko)

The philosophic exercise of likening oneself to God in that the direction and meaning of your life is yours alone to determine. The admission to oneself that anything and everything you know to be true may in fact be false, and that you do not possess the knowledge to determine what is and isn't. The method of continually constructing personal arguments for your decisions despite the knowledge that what you do may or may not matter.
These are two conversations about existentialism.
"Do we exist solely as figments of the imagination of God?"
"Perhaps. Then is it possible that the characters of our own dreams and imagination are of a similar nature to ourselves?"

"Life is meaningless. I should skip work in the morning to drink and enjoy myself."
"No, perhaps you should be responsible. You never know when you might find out the reason why."

Having to do with existence. More specifically, one way it is used is to mean having to do with state of being as opposed to truth or knowledge. An "existentialist" is more concerned with how to "be" than with what is true. A good example is Albert Camus's "The Plague", in which the character determines that we can't know the meaning of life and suffering, but we should just do what we can.
I think your problem with God is an existential one, not a theological one. You You know all you need to know, you just don't live it.

Existentialism is the reason why the people with the highest I.Q.s in the world go traveling in tibet then become garbagemen.
"I used to think Eistein was smart, then I read about existentialism and I don't beleive in the word smart anymore."

The other definition here is correct to a certain extent but it is really much more than that. It stresses individuality and freedom of choice but it also stresses an individuals responsibility to the choices he makes. Also discards all religion as a means to control human behavior. Existentialism is still a current movement but its most influential members came in the early 1900's. They include Sartre, Camus and Dostoevsky.
