"Fassbook" is a common name, used in Trinidad and Tobago, for the social networking site "Facebook". The word stems from a merging of the words "Fass" and "Facebook". A fass person is a very inquisitive or curious person(also known in Trinidad as a 'maco' or a 'macocious person').
The term was created to reflect the fact that Facebook is often used, by very curious individuals (macos), to investigate the personal lives of other people.
