The thread on "bitch" reminds me of a question I've been meaning to ask for some time: Is a "bitch slap" a synonym or an antonym for a "back hand"? I have always thought that a "bitch slap" was a slap that a woman would deliver: palm of hand applied to the other person's face. I assumed that "bitch slap" was the opposite of a "back hand" where the back of the hand makes contact with the other person's face. Some time ago, however, I saw a movie in which a man backhanded a woman and someone called this a "bitch slap." Now, I'm confused!
