To clean out one's excess friend list on a social networking site, typically arises when one realizes that they do not know or talk to 80% of the individuals on said list of people.
Parallels to the eating disorder bulimia in which one consumes massive amounts of food and proceeds to purge through vomiting, laxatives, exercise, etc.
Jon's going through a severe bout of Facebook Bulimia, he went from 1000 friends he barely knew to the 200 people he went to high school with overnight after purging everybody he didn't know faster than an overweight chick's eats her second lunch.
