Factard
A know-it-all who thinks they’re the smartest person in the room, even when they’re clearly wrong and everyone else is laughing at them.
‘I know more than you!’ even though he just said ‘cucumber’ instead of ‘cucumber.’
‘You’re all dumb, I’m the only one who knows the truth!’ after getting the question wrong.
‘I’m not wrong, you’re all wrong!’ while everyone else is rolling their eyes.
