What does propo mean in the Mockingjay?

"Propo" is not a word used in Suzanne Collins's "The Hunger Games" trilogy, including "Mockingjay." It's likely you're thinking of a different word or there's a misunderstanding.

Can you please clarify what you're looking for? Perhaps you meant:

* Prop - This is a common term for an object used in a film or play. It's possible you were thinking of a prop from the "Mockingjay" movie or books.

* Propaganda - This is a term used to describe information, especially of a biased or misleading nature, used to promote a political cause or point of view. Propaganda is a central theme in "Mockingjay."

Please provide more context about what you're trying to remember or ask about, and I can help you further.
