Used to describe a female ("Other Woman") whom you definitely prefer not to think about when 'referencing' them to your family, friends, co-workers or acquaintances as the person your boyfriend or husband left you for or is sleeping with. Can also apply if you're a gay or a bi-sexual female and another woman is sleeping with your past/current partner or lover.
