They know the ins and outs of a 'Verse or several 'Verses (the Buffy-Verse, Trek-Verse, Westeros-Verse, etc.), and have no shame in having that be a part of their identity. (Because, um, why should they? Knowing things rules.) By comparison, a dork is someone who is admittedly unsmooth or maybe lacks the social niceties (i.e. Emma Stone's whole schtick). Finally, a nerd pushes up their glasses and digs into a particular subject, prizing intellect above all. So, we want to know, are we right? What are your distinctions?
Or should we combine them all into one super-persona, and call it a "Gernork"? (For the record, we are definitely gernorks. Gernorks for President, 2024!
