When someone does something on Facebook just to make a point, or have everyone else see it. Can be done by a status, or joining of a group. Usually not a direct comment or wall post.
Facebook news feed: Brain just became a fan of "Harvard Business School Class of 2014"
Carlos: Man, Brain is such an asshole, he just wants everyone to see that and rub it in their face. He's just conspicuous facebooking like always.
Status: Meg just got a 2400 on her SAT!
Julie: Meg is such a jerk, everyone knows she's a fucking genius, why does she have to gloat all the time?
acting in a manner that would cause great suspicion that you are from another time
It's no wonder that when Brayden travelled to the Victorian era, they knew she was from the future. Her cell phone and laptopmade her extremely time conspicuous!
Obvious and unnecessary broadcasting of ones thoughts or feelings on using facebook, or a similar social networking site, as a medium. Especially on another's profile.
Sam: WTF Kelly is all over my home page with how much he misses everyone.
