Bill O'REilly, host of the non-biased, non-partisan show "The O'Reilly Factor". An extreme moderate, this man has liberals thiking he's a conservative just b/c of his level of fairness. But his books/radio show show that he's a moderate... maybe even a little liberal.

The act of a fact being completely twisted. The person, after realizing his mistake, will deny his fallacies just to be a stubborn ass.

The source of the term comes from the O'Reilly Factor, from its constant use of misconstrued facts.

John: Fuck that! Wikipedia is usually wrong anyway!
Ethan: You're a asshat, you know that?
