1: someone who abstains not only from eating meat, but also milk, eggs, and anything else derived from animals.Note: Not to be confused with a Nazivegan , who follows a vegan diet but flaunts one's veganhood over everyone else as if it is somehow morally superior. Kinda like saying that a gazelle is morally superior to a lion because the lion is a carnivore, you know? They're not better than each other; just different.
