Pahshon
A Pahshon is a Nahshon person who thinks they're super smart and will explain the obvious just to make you feel dumb.
'You didn't know the sun comes up in the morning? You're a Pahshon!'
'I told you that 1 + 1 is 2. You're a Pahshon!'
'You still don't know the days of the week? You're a Pahshon!'
