"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

A "Design Pattern" is really just a fancy way of saying "a standard solution to a problem".

Okay, there is a little more to it, but not a whole lot (and I'm likely to be burned at the stake as a heretic for saying that).  It all falls back to a book http://www.amazon.com/exec/obidos/tg/detail/-/0201633612/103-5906391-5428643?v=glance which came up with the idea to find a nice standard way to describe these solutions so it is easier to figure out which solution you need and to catalog the solutions you have.  It sounds obvious, but every idea sounds obvious after someone comes up with it.  It was considered pretty brilliant when it first came out.

Here's a simple overview: http://www.cs.wustl.edu/~schmidt/patterns.html

One particualr definition is:

Design patterns are recurring solutions to software design problems you find again and again in real-world application development. Design patterns are about design and interaction of objects, as well as providing a communication platform concerning elegant, reusable solutions to commonly encountered programming challenges.  

The Gang of Four (GOF) patterns are generally considered the foundation for all other patterns. They are categorized in three groups: Creational, Structural, and Behavioral.

Examples of design patterns are Singleton, Factory and Observer
