Thats right, you can run around calling people bitches and assholes and no one can stop it for a good hour, even then, do it on a newb on a proxy and have endless hours of fun.
What you do, to say bitch, is type the letter b, then, you hold down alt, and on the keypad, press (while holding alt) 255, and then let go of alt, and if done correctly, nothing should of came up.
Then, type the rest of bitch, and press enter.
The same works for asshole, but type assh at the start, then ole after 255.
I'm not sure what other words work, but experiment, and have fun
