Someone who believes that knowledge is not possible for themselves, some to different extents. They may believe that knowledge is possible, but paradoxically, it's impossible for them to know. While one will confine this to the metaphysical, most famously, regarding the existence of God, others will believe that they can know nothing at all, as not even their senses can be trusted.
Agnostics are often well-educated, and even more often do they see themselves as such. An agnostic, by virtue of their belief, typically sees themself as a very skeptical and critical person, and indeed, they usually are. They are often more intelligent on average than those who believe they know things, or at least, so the stereotype goes. Because of this, they often develop a sense of superiority, by which they can logically and rationally transcend the arguments of less-intelligent theists, who tend to be the most vocal ones.
An agnostic esteems above all else the scientific method. It is the infallible absolute of the agnostic. Everything must be empirically demonstrable to an agnostic, or it cannot be known to exist. A typical argument an atheist would use against a theist would be: "Since you cannot prove the existence of your God, how do you know that he exists?"
An agnostic attempts to apply empiricism to absolutely every aspect of reality. A thing does not exist unless it can be "scientifically proven". A modern understanding of science is the typical rhetoric of the agnostic.

Theist: "Do you believe in God?"
Agnostic: "I do not, because it is impossible to prove the existence of God. In fact, I do not believe it is possible to prove the existence of anything, as everything we've known is a product or our subjective consciousness."
Theist: "Are you sure?"
Agnostic: "Yes, I am 100% sure."
OR
Agnostic: "If a thing cannot be proven scientifically, there is no way to know that it exists"
Philosopher dude: "But you are assuming the existence of knowledge, which in itself is a totally abstract concept that is entirely unprovable by those means. If you are to apply the scientific method to every facet of knowledge, with our current understanding of perception and cognition, it would be impossible to trust your own senses, and everything would be unprovable, and hence, you could know nothing at all, including the validity of the scientific method."
Agnostic: "Any ideas of yours cannot be empirically proven, so I need not listen to you."
Philosopher dude: *facepalm.

Get the Agnosticmug. A person who believes that there may or may not be a god, they may decide later on in life if there is or is not. They are not atheists without balls. And they want proof before admitting or denying God.

Get the Agnosticmug. It's Greek, and it literally means "without knowledge." (a=without, gnossos=knowledge). An antipathy towards religion and/or the existence of God.
