Why is 'fuck off' or 'fuck you' a bad thing??? I usually find that activity quite pleasant.
You could expand on that.
Why is it a bad thing to be called a boob, or a pussy? They are lovely things I most enjoy. Being called a Dick? I have one, it's Nice to have and very dear to me. Being called an ass or an asshole? Asses can be beautiful, and everyone has assholes. They are quite usefull to THE human existance.
Stephen fry once remarked in Some clip that it's strange we take all these wonderous things we use for enjoyable recreation and even to bring forth THE miracle of new life and feel THE need to censor them. (Paraphrasing here.) Yet we feel most comfortable saying words which concern THE darkest, worst aspects of humanity. Words like torture, tyrant, kill, ... . 'Work was torture'. 'My Boss is such a tyrant.' 'Yo man, you killed out there!' All these words get a free pass from everyone. But say 'Work was shit'. 'My Boss is a dick.' Or 'you fucking ruled out there.' In front of someone sensitive or someone With children, (All natural human parts and behaviors,) and there is a Good chance you'll get called out for it.
