A jargonaut is someone who uses jargon too much.
Yes, it's a piece of jargon that belittles those who use jargon.
Now, is that a piece of post-modern brilliance? Or simple hypocrisy?
I know what I think.
Sunday Rest: jargonaut. This word, of course, is an echo of argonaut, which describes one of the men who sailed on Jason's ship the Argo, which was named after its builder Argus. The Greek naus means ship. The word jargon came into English from French, and is, pleasingly, basically the same word as gargle.
