Mobile Army Surgical Hospital. Made famous by a long running TV Series of the same name.

M*A*S*H

was a book and a movie BEFORE it was a "hit TV series." Both of these were just as entertaining, if not more so (in their own mediums).

M*A*S*H starred Donald Sutherland, Elliott Gould, Sally Kellerman, Tom Skerritt, and Robert Duvall.

M.A.R.S.

Morning After Remorse Syndrome. The feeling of regret about the previous night's alcohol-induced activities. M.A.R.S. can have direct causes, such as engaging in buffoonery, or can be a general sense of remorse not attached to a specific incident. M.A.R.S. can exist separate from a hangover, as its effects are purely mental and emotional, rather than physical. (pronounced mahrz)

Guy A: Ah man, I have a really bad case of M.A.R.S.
Guy B: That's probably because you hooked up with that butterface and drunk-dialed your mom.
