I'd like to run with that and propose the word *ghojwI'qoq*. A *ghojwI'qoq* would be something who is learning or at least dabbling in a field of endeavour/study, but is really a poser. Perhaps "great pretender" might be a translation of *ghojwI'qoq*. And then there's "Profundus Maximus":

Check out Mike L. Reed's description of the Profundus Maximus type of flame warrior above. That might be the best way to translate *ghojwI'qoq*.
Or would that just be a *ghojwI ngeb*?
