http://en.wikipedia.org/wiki/Lorem_ipsum
In publishing and graphic design, lorem ipsum is standard placeholder text used to demonstrate the graphic elements of a document or visual presentation, such as font, typography, and layout. Lorem ipsum also serves as placeholder text in mock-ups of visual design projects before the actual words are inserted into the finished product. When used in this manner, it is often called greeking.
Even though using "lorem ipsum" often arouses curiosity due to its resemblance to classical Latin, it is not intended to have meaning. Where text is visible in a document, people tend to focus on the textual content rather than upon overall presentation, so publishers use lorem ipsum when displaying a typeface or design in order to direct the focus to presentation. "Lorem ipsum" also approximates a typical distribution of letters in English, which helps to shift the focus to presentation.
