macolyte
A person who thinks all other computers are trash and will argue about it for hours, even when they're clearly wrong.
He spent 3 hours arguing that Windows is trash. I asked him if he was a Macolyte. He said yes.
She said her Mac was the best ever. I said, 'You're a Macolyte.' She smiled and said, 'I know.'
He would rather burn down a library than admit a PC is better.
