Have you ever gotten something in your mind and started seeing it everywhere? Probably, because this is a version of synchronicity, or perhaps confirmation bias.
Well, what I'm seeing is horse feathers, which means "Nonsense". I don't like to swear, so I was talking to my sister-in-law about Scott Adams's B******* Filter and she suggested calling it the Horse Feathers Filter. I ran with it. Now, I'm seeing Horse Feathers everywhere!
