I think it's the intent and commitment that defines it. Someone who does not, as a rule, consume meat or animal products is vegeterian. I think that's true if they do it for one day or a thousand, and IMO it's also true if they occasionally consume an animal product due to necessity or ignorance or mislabeling. By contrast, ~80% of my food intake right now is Soylent. I could make that 100% if I wanted, and I suppose that would qualify me as vegeterian; Soylent contains no animal byproducts. But I don't consider myself vegeterian and never will. Edit: I tend to look at this like a religion. Can someone be Christian if they aren't in church every time the door is open? Do they have to follow every rule and think correctly and so forth 100% of the time? I think most people would say no.
