The word mc means curious of own sexuality, and is usually positioned in front of somebody's name. Mc is also translated from scotish to english as, sam. Mc can also mean beast if used in the right sentance, "I am a mc". Sometimes Mc can mean there is a scary man standing behind somebody. "SamMc" = sam there is a scary man standing behind you.
For example Sam Mac will become Sam McMac as he is curious of his sexuality.

To add MC in front of any word makes it that much more intense. It gives more meaning and more excitement.

A prefix placed in front of a noun to connote an inherent attribute of either malaise, homogenization, gratuitous commercialism, mediocrity, or any combination thereof. In other words, add Mc to any noun to give it a tincture of everything the McDonalds empire has given to (or taken away from) the landscape of American culture.
