Factually
A combo of fact and actually. Use it when you're trying to convince someone your dumb idea is actually real.
'Factually, I am the best at video games.', said no one ever
'Factually, I didn't cheat on the test.', said the guy who got a 32%'
'Factually, I'm the king of the world.', said the kid who won the spelling bee'
