It was only a temporary ban so you should be able to rejoin by now.
The "it means something else" has never saved anyone and never will. You were asked not to use the word, and you decided It would be a good idea to use it again while trying to argue with the admins. If you don't agree with an admins decision, send Deofuta, LittleGuy, or I PM with any evidence you may have.
If you want to run around calling the first artillery guard FAGs, then do it on a different server.
Be sure to reread the rules as to not be banned again.
