Bitch
a female dog; (for a woman) someone who is malicious, spiteful, or unpleasant
Old English
From the word 'bicce', meaning female dog.
I was waiting in my car in a huge traffic jam, next to the ring road exit. I asked the person in the next car over what might be the issue. He said, “Its that bitch going home” He meant Maryam Nawaz Shareef, the CM!
This is not unique to me. Ask any working women in an authoritative position and she has been called the B word to her face, within her earshot, and behind her back.
