Private communication: Try not to use language that is considered offensive. You can certainly joke around with your friends, but if someone complains or asks you to stop, either stop or go someplace else. Public communication: Do not use obscenities or vulgar language in shout and other public channels, including obscenities censored with obfuscating characters such as "@" or "#". Do not create characters, zombies, groups, etc. with names that would be considered foul or indecent. Do not create insulting or graphic character descriptions for yourself or a zombie, etc.
