Vegetables? Forget it. If you're into eating meat, meat and more meat, then you're carnivorous.
Not surprisingly, the adjective carnivorous can be traced back to the Latin word for "flesh." Carnivorous eaters get their fill of other animals, so they've also got a reputation for being savage or predatory. So anyone who stalks around like a lion on the hunt could also be described as carnivorous, even if they're a card-carrying vegetarian.
