A person who yells at you about your birthday being wrong because Facebook said so even though you were born on a different day and they probably changed it just for fun.
'You were born on the 15th, not the 12th! Facebook said so!'
'I changed your birthday to April 1st because it was a joke and now you're mad!'
'You're not born on the 3rd, you're born on the 5th, and I know because Facebook told me!'
