A way of describing a powerful, no nonsense lady (usually the boss) in the workplace, usually when kicking her staff into shape. Not necessarily a bitch, may or may not be a babe, may or may not be wearing heels or boots at the time of sorting her staff/the problem out. Not language advised to be used in front of said boss, although it is generally considered a complement.
Guy 1: "Lynne put her bitch boots on and sorted the problem out."
Guy 2: "Sweet!"
