Primarily, a living creature who consumes meat - i.e.: poultry, pork, beef, fish. Many human meat-eaters are disrespectful towards those who don't eat meat, particularly towards vegans, often writing bad definitions of them in urban dictionary. Such people are often bad at spelling and consistently illogical in their responses to vegetarians and vegans.
Omnivore: 'I could murder a nice, juicy steak. Do you want one?'

Vegan: 'No thankyou, I'm a vegan.'

Omnivore: 'Oh, one of those. I suppose you're going to lecture me on how bad it is to eat meat.' (waves meat in vegan's face).

Vegan: (looks at omnivore disdainfully) No, but I would prefer it if you didn't wave meat in my face. (Waves tofu burger in omnivore's face).

Omnivore: (Shrinks back in true terror).

sanus omnivorism is the practice of comsuming only healthy amounts of any kind of meat products for example only once a week. This eating habit was developed after scientific findings proved that vegetarians often lack supply of certain nutrients like iron that are hard to find in plant foods.
I became a sanus omnivore after discovering that I don't get all the necessary nutrients I need when being a hardcore vegetarian
