You score a facebook hat-trick when you write down "what are you thinking/doing?" box, then click "i like" and then comment on that what you liked and wrote about it...
when someone reaches that he or she should very proud of him/herself as if they scored acctual hat-trick...
"Hey you saw what a dusche bag Tomy is?"
"no, what he did?"
"he scored his fifth facebook hat-trick today!!!"
"wow, someone has his ego boost today!"
when a person labels someone in a blank photo on facebook with a sexy caption then writes in the description that you need facebook gold account to see it. this leads everyone on a quest to find something that does not exists
Bob: Jim taged megan fox and lisa lipps in this picture but I can't see it because I don't have facebook gold!
