I'm sure you guys already know what it is, but for the sake of making this thread's opening post at least somewhat substantive (which I am not good at XD), I'll include its definition:
"The principle or practice of excluding all meat and fish, and sometimes, in the case of vegans, all animal products (such as eggs, cheese, etc.) from one's diet"
(Source: http://www.thefreedictionary.com/vegetarianism)
I was a vegetarian for about eleven years or so, but tried meat one time (I don't remember where, honestly XD) and have loved it ever since. I don't eat it very often, though, since I'm the only one in my immediate family who likes it. I personally think vegetarianism is a healthy lifestyle; it just isn't for me.
My opinion is boring. I want to hear yours!
