when somebody says something and it is on facebook
Him and i are dating its facebook offical.
When one posts something on Facebook or another internet blog site it becomes offical. The reasoning is that one posts information on the internet for all to see leaving little doubt that it didn't happen. Mostly used in the context of dating.
Person 1: Are Jordan and Julie going out?
Person 2: Well I saw them making out in the hallway but I am not going to say anything until it is 'Facebook Offical'.
