Bitch为婊子,用来骂人（雌性犬科动物）的英文。现在也可以用作是贬低或厌恶部分女性，意思则是辱骂女性下贱，也有批评之意；也可用于男性。也是这个字出自1150年代的bicche，由古英语词bicce发展而来，并可能演变自古冰岛语的bikkja，《牛津英语词典》指出该字在西元1000年左右意思是「母狗」。

和中文的婊子用法类似。美国动画《南方四贱客》其中一集阿ㄆ一ㄚˇ辱骂凯子的妈妈为Bitch，以歌唱方式说出「Kyle's Mom's a Bitch」（中文播出时翻译为「凯子他妈是婊子」）等内容。

Bitch, literally meaning a female dog, is a slang pejorative for a person, commonly a woman, who is belligerent, unreasonable, malicious, a control freak, rudely intrusive or aggressive. When applied to a man, bitch is a derogatory term for a subordinate. 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.
