Top definition
An individual who uses facebook to constantly promote themselves. This person has around 2500 friends and usually calls them his "gang" or "posse" even though these people are all virtual and are not real friends. The individual will post time again how great everything about their life is, even though it is fantasy lies. An insecure, weak minded facebook addict.
facebooker#1: That guy Les is always posting his greatness on the wall, what an idiot!

facebooker#2: Yeah, to be an elementary school principal, he sure is a facebook prima donna.
