Facticle
A facticle is a person who talks too much about things they barely understand, especially science stuff. They act like they’re Einstein just because they know what a proton is.
'A proton is a particle. It has a positive charge. Also, it's in atoms. Also, atoms are in everything. Also, everything is made of atoms. Also... also... also...'
'Why is the sky blue? Because of Rayleigh scattering. Also, that's a thing. Also, it's a real thing. Also, it's a very real thing.'
'You said 'hello' like it was a scientific experiment. I'm not even mad. I'm just confused.'
