O'reillying
A word used to call someone an idiot. You can only say it after someone does something so stupid it makes your brain feel like it's melting. It comes from Bill O'Reilly, who's probably the dumbest man alive.
'That's the dumbest thing I've ever heard! You're an O'Reilly!'
'He just said the dumbest thing ever. He's an O'Reilly.'
'That idiot just said the dumbest thing. He's an O'Reilly.'
