What does "battle slash" mean? Or does it just mean that he slashes his enemies with his lightsaber in battle?

For the deeper explanation:

Basically, this is tough. I rewrote my answer like 3 times and kept deleting it.

So, "battle slash" has no real meaning. If I were to give it a meaning, it would be a childish way of naming an attack. Like, imagine you're 5 years old playing Star Wars with your friend, and you're Yoda. You go in for a big attack and yell "YODA BATTLE SLASH!" as you dramatically swing at your friend. That's how I view the phrase, "battle slash." You'll probably never see "battle slash" used outside of video games or cartoons.
