Facebook's Friends Day reactions monster is here to terrify us all

While International Friendship Day was popularized by greeting card companies, Facebook went a step forward and coined its own birthday, Feb. 4 as Friends Day a few years ago.  

Facebook, which has finally turned old enough to be a user on its own site, is marking the made-up holiday by bestowing its users with a personalized Friends Day video. The videos are similar to other auto-generated videos Facebook has done (like the ones for birthdays). with an eye-popping addition: a bizarre-looking humanoid creature, an apparent amalgam of reaction buttons and Facebook photos.
