Facticle
A facticle is someone who can’t help but add facts to everything, even when no one asked. They’ll ruin a simple conversation with five extra facts.
'You said 'hi' like it was a big deal. Also, deals are things. Also, things are important.'
'I said 'yes' like it was a scientific discovery. Also, discoveries are things. Also, things are cool.'
'You asked 'how’s your day?' like it was a research project. Also, projects are things. Also, things are important.'
