Carnevarian
A person who eats meat and animal proteins as their primary source of nutrients.  Related to the Meatatarian, however the Carnevarian believes that eating vegetables is cruel to plants.  Just because you can't hear their cries doesn't mean they don't feel.  At least in the killing of animals for meat you are honest with yourself.  Carnivarians are the anti-vegetarian, and do not tolerate Vegetarians / Vegans telling them what they can and cannot eat.
Veggy Velma: "How can you eat that steak?  Don't you know the suffering that poor cow went through?"

Meaty Mark: "How can you eat that salad?  What about the suffering of those sprouts and lettuce as they were ripped from the ground?"

Veggy Velma: "They don't feel anything.  I'm a tree hugging vegetarian.  I care about all the animals."

Meaty Mark: "I'm a Carnevarian, and I am honest about where my food comes from.  Don't tell me how to live, and I won't tell you."
