Get a boss fight mug for your girlfriend Nathalie.
A physical confrontation that is so one sided due to a large gap in skill, physical power, or experience, that it resembles the iconic fight scenes (before the final battle) between The Boss and Naked Snake in Metal Gear Solid: Snake Eater. In "The Boss" Fights, major injuries such as fractured ribs, broken arms, snapped fingers and severe trauma to the eyes are inevitable.
