It stands for male incapability syndrome. It's that men have a reduced mental capacity that warps their perception of reality and ability to reason. They have a terribly deluded sense of self-importance, which makes it very difficult for them to interact with more intelligent life-forms. Men are simply not as evolved as women.
On my way to the party I was preparing myself for the interaction with the mis that would be there.
