A metaphor for unsubstantiated propaganda that is created especially for political motives and disseminated through mass media, blogs, emails and whisper campaigns. A "fragile shell full of excrement and hot air" that is easily debunked, or "popped", leaving the bearer embarrassed, or "covered in excrement once it's popped" as they hold it.
I got an email about President Obama's "$200 million dollar a day trip" to India; I popped that turd balloon with one Google search.
