look up any word, like tribbing:
 
1.
A vegetarian who eats eggs. Even those who become vegetarians for moral reasons can eat eggs, because those sold as food are not fertilised and can thus never develop into birds.
Alice: Can I get some egg salad over here?
Bob: Egg salad? I thought you were a vegetarian.
Alice: I'm an ovo-vegetarian, actually.
