I have not seen anyone say that word or be warned about it. It sounds like you may have been saying it an awful lot though, and I wonder if you have some need to keep on saying it or if it kept you from racing or if it annoyed any guests or admins. Basically if you were saying it too much or using it in way that was not right then the admin may say something about it. If the admin asks you not to use it then you should not.
Thanks for coming to the forums and asking about it, I personally don't have a problem with that word, but if you kept on saying it, I may ask you to stop as it would be pointless and annoying. What is the point of repeatedly typing out a word like that anyway, I don't think it benefits you or any of the guest to keep on repeating it. Sure to say something in frustration is one thing, but over and over again makes no sense unless you are just trying to test the admin and push the line of what you can do. And yes there is variation from admin to admin and this is normal.
