I find that people always want to know why you're a vegetarian. Honestly, for me, there are a ton of reasons and many of them are not quite dinner table conversations, especially when meat-eaters are involved as it grosses them out.
Once with a good friend, when she said "rabbit food", I said "dead body" pointing to her chicken. That was childish of me and she obviously didn't like it. So it is possible to make fun and even annoy meat eaters, but it would only end up straining the friendship (or whatever relationship) and nothing will come out of it. The best thing to do is to just smile and keep eating.
