factimonious
When someone throws facts at you like a punchline, but with more swearing and less sense.
'You're wrong!' he said. I said, 'You're factimonious, and I'm still right.'
'That’s not a fact!' she yelled. I said, 'It’s factimonious, and you’re a dummy.'
He said it was true, I said it was factimonious, and I had a snack.
