The measure and/or condition of one's bitchiness. Used to describe a bitch. Commonly includes quantitative values between 1 (the least amount of bitchiness) to 10 (the highest amount of bitchiness). In some severe cases a bitch may reach a bitchitivity level of 11, in which case a pimp hand should be used on said bitch.
Goddamnit, Rebecca, your bitchitivity is getting out of hand!
