That's not the type of BS the author means, what you're referring to is called "falseness" by the author, eg. deliberate misleading statement. BS is more like sitting around with people telling stories and embellishing with some details that are irrelevant, or in the more useful case, discussing an idea that is incomplete without fear of the potential falsehoods impacting the creative process of exploring that idea. Say you're unsure of which car to buy, you could BS it in some story about your cousin buying that car (cousin actually bought a truck but that isn't the point of the story) and see how the people around you respond to it. Everyone who hates that car, while BS'ing with you is free to state it, but when you own that car already they have to hedge their opinions.
