lo-vegetarian
n.— «Gradually, “lacto-ovo vegetarians” grouped and shortened their title to “vegetarian.” This is why I sometime use the term “lo-vegetarian” where the “lo” stands for “lacto-ovo.» —“Why vegetarianism is ethically the same as eating meat” by Adam Kochanowicz in Omaha, Nebraska Examiner.com Mar. 27, 2009.
