Another useful1 term for describing one's preferred eating habits:
- Vegetarian once removed
- Someone who only eats vegetarian beings.
Developing a coherent, consistent scheme that provides natural definitions for the terms quasi-vegetarian, para-vegetarian and meta-vegetarian is left as an exercise to the reader. (Bonus points if you also manage to include flexitarianism as a distinct concept.)
