What you would say to any douche-bag attacking you in a dismissive, bias, ignorant, hypocritical, narcissistic, distortive and incriminating way, much like the douche-bag commentary of Bill O'Reilly.
Guy #1: Dude, I've lost so much respect for you after you called my girlfriend a bitch.
Guy #2: But you said that she was yourself, remember?
Guy #1: That wasn't what I meant.
Guy #2: You're such a hypocrite; you know perfectly well that I was just backing you up after you said it, so get off your high-horse and Don't O'Reilly Me, asshole.
Guy #1: We need to cut to a commercial.
1. Any frumpy over-60 white male who loves a large dildo up his ass while talking dirty to employees on the phone.
2. To cram a large dildo up your ass while having phone sex.
"Honey can you repeat that? I wanna do a "bill o'reilly" for the full effect."
