To be offended. An evil state of mind that causes censorship, kills freedom of speech, destroys urban dictionary definitions (via the remove button), and ruins video games as well as many other things.
People who are able to by "offended" by anything are the worst people on earth. Keep an open mind about things and live and let live. Don't ruin things for other people just because you can't take it. Not everything is pleasent in this world and if you can't take it then you need to grow up.
