Putting a label on yourself is not necessary. You do not have to be one way or another just be who you are. But as far as being a vegetarian, that means that you abstain from consuming meat products. No chicken, beef, pork, turkey, alligator, or anything that has at anytime been able to taste you back. There are what people like to call lacto-ovo vegetarians that eat eggs and cheese.
But the point here is if you are just looking to eat healthy then eat however you want. But if you are looking to label yourself then you can just research being a vegetarian on the internet of pick up some books.
Also, I am glad to hear that you love purple koolaid and watermelon... good for you! Whatever that has to do with this question. :-)
