Also known as a woman.Usually, a man's MSMD is his girlfriend, wife, mother, or a prostitute.
The role of a MSMD is to always have a sandwich prepared for the man during all times of the day. Generally, a man should only accept fresh sandwiches that our prepared in less than two minutes. However, if the MSMD is going to be busy during a man's sandwich time, then it is her responsibility to prepare multiple high quality sandwiches.
In rare cases, the MSMD will leave the man sandwichless. If this occurs, the man has the legal right to dispose of the MSMD in any way that he sees fit.
