A term for when a girl is on her period and if you piss her off she will bite your head off. Sometimes two girls can be in bitchmode together, and that is more dangerous for the male specimen. It is even worse if the two girls are best friends. Bitchmode gets more intense as the menstrual cycle progresses. Hint: don't mess with a girl in bitchmode because it will end badly for you.
