Maybe we should call it a PMOU.

I had a few alternate titles for this one.  Both seemed a little more obtuse than PMOU which sounds sort of like a project management IOU.  If you're headed down this route, I think things have gone seriously astray (and this is one with a basis in reality).  It might smell like a charter, all agile like, but a charter is a general roadmap and agreement amongst the team at the beginning of a project, not a document to enforce how teams interact with each other.  That sort of rigidity falls apart very quickly, particularly when imposed by a third party.

• Alt: So the M stands for monologue?

Snarky: The PMO needs you to agree to the Memorandum of Understanding between development and testing.  We've determined that it's the only way to align department expectations.
