Yep that's the other thing with bullying. Most people will experience some form of it, but in generally there's one category that's just light-hearted dumb jokes you can ignore (and are not even directed specifically at you - the person is being an asshole to everyone without a specific focus), and a second category that picks on a particular point - a point that's different enough about yourself that makes the bullying acceptable to the rest of your peers; in which case the best course of action is to correct that difference.
