One who will brag about being a vegetarian but is often seen eating meat, burgers, cheese etc.
Scene at a restuarant:
Georgina: Do you have any Vegetarian Meals? I am a Vegetarian.
Waitress: We have salad....and Water.
Cam: What the...! Are you Vegetaragain?...I saw you eating a beef kebab last night drunk on Baileys and Milk...Whenever we go out with your trendy mates you always turn VegetarAgain.
