How do you play BS?

Please provide me with more context. "BS" can refer to many things, like:

* Bullsh*t: This is a slang term for something untrue or insincere. If you're asking how to play a game involving this, I need more information.

* B.S. in Business: This is a Bachelor of Science degree in Business. It's not something you "play."

* BS: Could be an abbreviation for something else entirely.

Tell me more about what you mean by "BS," and I can help you understand how to play it.
