Don't make eye contact

I've got questions about this picture.  First, is this one of those people you try really hard not to make eye with because their combination of self-assurance and vomitous trivial monologue is overwhelming? Or is this a genius networking opportunity? Post grad who misses hanging out in the ivory tower and hopes to relive the days where he was smarter than everyone again and again? Or just bored?  Does he start charging after the first 30 minutes?

I bet he's lonesome. Still I'm not making eye contact.
