Top definition
An alternate name to the popular social networking site Facebook which was "created" by the egotistical Mark Zuckerberg. Facebook today has over 700 million users mostly due to the fact that it has been freely advertised on every news program, television/reality show, website, and consumer product. This has inflated Mark Zuckerberg's ego even more than humanly possible and caused some people to believe that he is the Second Coming of Bill Gates.

Sometimes pronounced "suck" book.
