If you look to the lifesaver on the page where the regional discussion threads are listed, it has a FAQ.  There are two pages of definitions there for all of these obscure acronyms.  CIM, DATY and MSOG were ones that I remember puzzling over for weeks until I finally found that list of definitions.
(BTW, CIM is cum in mouth, DATY is Dine at the Y, and MSOG is multiple shots on goal- who thinks this stuff up?).

and mp means you prefer madame patricia!

I assume you actually knew that MP, (I did see the 'lmfao') but then you could have said Russian means you prefer Russians too
