Today, my cafeteria within the university's research building, actually had a food station labeled for "flexivores." What's a flexivore, other than a made-up word? According to the creators of this word, a flexivore is a person that eats meat, but chooses to incorporate less or no meat meals into his diet.

AND, if we're going to name it, why not flexi-VORE instead. since it's more like an omnivorous diet than a vegetarian one.
