I don't think it's malicious. I often find that as I think about and re-categorize things, meanings of words shift until I'm thinking and occasionally talking in my own private vocabulary. It's rude at best to let it out in the open, but primarily because it's lazy. Inventing new vocabulary is a lot of work, and also has its own fundamental difficulties. People who divide the world into different categories are kind of screwed when it comes to communicating their ideas. IMO this is one of the thorniest problems in all of communication.
