It's been explained in my presence by a guy who is a genuine tested genius this way:
In men, things are a straight shot through the body. Ok, things go into your ears, you apply logic and they go straight through your body and out your ****. It's a straight shot and clear thinking.
In women, things go in the ears, into the brain, logic is applied, it goes through the body and into the ****** where it gets screwed up and doesn't know where to go and it ricochets around and is messed up.
The ****** is a logic distortion device.
