The Most Common Full Form of MF
The most common full form of MF is motherf***er. It is a strong curse word, so the abbreviation carries the same edge, even though only two letters are visible.
The MF slang meaning is rarely literal. Most of the time it works as an intensifier or a label for a person, and the feeling behind it comes from the rest of the message.
