A contraction of the words "Facebook" and "activist". A hashtag warrior who truly believes that their likes on pictures donate money to poor kids in 'Africa'.

Can also refer to a person whom honestly believes their hashtags can magically take human form to fight for human rights, and that Boko Haram (aka Trey Songz) will bring their girls back.
Noun: There go them faktivists again. Sorry Nigeria, I will not bring back your girls.

Verb: Yo, can someone tell Lucy to stop faktivising. Trey Songz ain't bringing your girls back. #ItsMrStealYourGirl
