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.
