What does you like a man who grins when he fights mean?

It can be simply be about facing adversity with a positive outlook.

Or. It can also be about how anger is often just guarded fear. Guys get aggressive, but not taking it too seriously is key - otherwise people end up dead, and girls hate that, so not sexy. Anyone that had some toss ups with brothers or friends knows this. Anger is also energy, so use it wisely. A man that grins when he fights isn't even giving the other person the satisfaction of getting him upset. It shows confidence, perspective, but not fear. That's appealing.
