Facebooktarian
“Facebooktarian” refers to someone who pretends to be a vegetarian, creating a fake image of himself in social networks (mainly Facebook), posting pictures of a healthy lifestyle, while in real life he/she actually eats all kinds of unhealthy food (including all types of meats) and doesn't care much about his health.
My friend Jose is a facebooktarian, always posting really veggie pictures on his timeline but actually he eats every kind of meat.
