Bitch (insult)
The word "bitch", literally meaning a female dog, is a common slang term in the English language, especially used as a denigrating term applied to a person, commonly a woman. It often refers to someone who is belligerent, unreasonable, malicious, rudely intrusive or aggressive.
Its original use as a vulgarism, documented to the fourteenth century, suggested high sexual desire in a woman, comparable to a dog in heat. The range of meanings has expanded in modern usage. In a feminist context, it can indicate a strong or assertive woman, one who might make men feel threatened. When applied to a man, "bitch" is a derogatory term for a subordinate.
