As I grew up a bit and discovered it was not necessary to use such crude language, that expression became "BS."

Q. What did It really mean when I used those expressions?
A. It meant that something was ridiculous, idiotic, a lie or just stupid. It covered any number or negative formats. The dictionary defines it as:
nonsense; especially : foolish insolent talk...

I have decided that I no longer will use either of those expressions in the future. When I have a need to express such feelings, I will use the word "Pelosi."

Let me use it in a sentence. "That's just a bunch of Pelosi."
I encourage you to do the same. It is such a good word. It really packs a lot of punch. We are no longer being vulgar. But it clearly expresses our feelings. If enough of us use it, perhaps the word could be entered into the dictionary. What an excellent legacy for the Speaker of the House!
