The other night I had a friend I hadn't seen in many years over. We got pretty drunk, conversation was flowing, and somehow it ended up at domestic violence. We both ended up agreeing that an open-hand smack is something that could be deemed as acceptable in relationships, depending on context, and it's equally acceptable for both genders to do so.

While this may come across as silly, I was wondering what you guys thought of this. If your otherwise loving spouse/girl/boyfriend raised a hand to smack you in a heated argument, would you consider it domestic abuse and dump them on the spot? Or is it acceptable depending on context?
