Facebook Entertainer
When your sole activity on Facebook is to comment or respond only to major events, rather than consistent / daily updating. In other words, you come out much like a clown, magician, or mathemagician and only appear (to post / accept invitations) at parties, birthdays, and Bar Mitzvah's.
