The phenomenon that occurs when someone, usually a female, losses their coolness for a temporary period of time. Bitchface mode can come on quickly and can even occur several times a day - more so during certain times of the month.
Example 1: "Whoa dude, your girlfriend is being such a Bitchface today!"
Example 2: "I work with the biggest Bitchface ever! If I knew I wouldn't lose my job, I slap her in her Bitchface."
