It's not that difficult or complicated.
And there certainly isn't a "multitude of definitions". There are a multitude of opinions, many of them wrong.
Males and females do practically everything different under the same circumstances.
A man and a woman goes to a large event - the woman looks around, takes in the scenery or the building it is in. Noticing all kinds of things in the surroundings. And commenting on them.
The man is looking at nothing but where they are supposed to go, that is the task at hand, and that is the priority for the male. Once the two are settled in, and they know where they are supposed to be - then the man might look around.
The woman thinks he doesn't care about the scenery, which is wrong. He does, but not till the task is finished.
That is just one sliver of an example of the many differences between the two sexes.
Behaviorally, we have little in common. But the differences are important, and work well in most circumstances.
