An individual who has decided they do not believe in a god or gods - most consider the idea of a god or gods as being an extremely remote possibility, to the point of being unrealistic, ergo atheist. As opposed to a theist who does believe in a god or gods, e.g. Hindus, Muslims, Christians, etc. Not to be confused with agnostics, who have not decided if they believe in the idea of a god or gods e.g. Thomas Huxley. Also not to be confused with anti-theists who are atheists that take an active stance against theism e.g. Richard Dawkins.
I don't believe in God therefore I'm an atheist.

A person who, unlike religious people, don't have imaginary friends (like Jesus).
A: Hey, look at that religious person, he makes-believe every day!
B: I know, that's kinda weird
A: Obviously the world wasn't created in 7 days. And if there was a God why are so many African children dying?
B: Yeah, atheists are so smart.

A person who either:

a. Does not have any theistic beliefs of any nature ("weak" atheism)
b. Actively believes that there is no God, or indeed any matter of supernatural entity ("strong" atheism"

There are two noteworthy things about the concept of atheism:

a. "Atheism", or a- in front of theism, simply means "not theistic". Therefore, the literal definition of the word atheism is what was referred to before as weak atheism. The differentiation between "weak" and strong atheism, however, is now necessary, due to the proliferation in use of labeling strong atheism as simply atheism.
b. "Belief" that there is no God is still the important point here for strong atheism. No reasonable atheist would assert that they KNOW there is no God, just as no reasonable theist would assert that they KNOW there IS a God - there is no proof for either preposition, and thus certainty is impossible either way. However, strong atheism relies on the fact that logically proving something does NOT exist is far harder than proving something does exist (and in fact is generally impossible), and thus tends not to perceive a lack of absolute proof that there is no God as a weakness in their arguments.
I am an atheist. This tells you nothing about my personality, character, or intelligence. All it tells you is that I do not have particular belief in God. That is all that atheists have in common.

Someone that believes that there is no god. Some are more tolerant than others some are more fanatical than others, just like in every other group in the world.

PS: To the Christians, we tend to comment on you the most because you tend to attack the most. I have yet to run into a Buddhist monk ranting about how I'm going to suffer for all eternity for not being Buddhist.
Someone less tolerant of others: Haha. You're religious?! Stupid f*cking loser.

Someone more tolerant of others: Oh, I see. You're religious. I'm atheist.

A very broad catagory of people that others may consider anything from unethical to logical. In truth atheism (a-lacking; theism-beleif in a higher power) makes up a large number of people with different beleifs. Not all atheists are such because they don't have proof that God exists.

I, for one, am atheist because I know that if I were Christian, and I ended up in heven, I would feel guilty that a good many people in hell were there for eternity because they grew up with one set of "heretical" beleifs and "were never taught better".

I beleive that hell is a punishment that people are told they will face if they are not good to their fellow man. This would be a good thing, however, if, say, a Native American, who did not beleive Christ was the son of God and did only good during his life, goes to hell, that defeats the concept.

Nobody has the right to say one child is born with "original sin" and the way to cleanse him is to pay the church.

I have many reasons to be atheist (and science is one of them). It is always better to judge the individual than to put everybody into about 25 groups and dictate their right to live on this planet based on that.
