Facticular

My cousin is a facticular. He can tell you the exact number of toes a sloth has.

I asked my teacher a question, and she said, 'You’re not a facticular, you’re just a human Google.'

At lunch, my friend said, 'Did you know the Eiffel Tower is taller than the Statue of Liberty?' I said, 'You’re a facticular.'

When I saw my classmate recite the whole periodic table, I had facticular. I wanted to scream and hug him at the same time.

My brother got facticular when he saw a guy know the history of every president.

I had facticular when my crush told me he knew all the constellations.
