Make Money Fuck Bitches

As in the way of life of a true gangsta. In the words of Lil' Wayne, "I be makin' money and fuckin' bitches". It is a way of life, whether gangsta or businessman. MMFB is what the best of us do.

mmfb

mmfb stands for my mother fucking box. It is a term used by soccer goalkeepers. It refers to the box they are allowed to pick the ball up in. The term means no one can come in and score a goal because it is the goalkeeper’s mother fucking box.

The goalkeeper took out the striker because they entered his mmfb.
