Student kept on saying Napolean needs to "Step His Game Up." Any definitions?

My class at HS #342 in the Upper East Side had a discussion the other day about the Napoleonic Wars...It was very heated with some students acting out some of Napoleon Bonaparte's famous speeches to his troops which quickly turned into a debate. Will suffice to say one student was upset about Napolean's bonehead move to take on the British at Waterloo...Sorry for all the backgound, but one student keep saying "that Napolean needs to Step his Game up" not once but about 5 times, sometimes he'd say "Step your game up" or "step it up" i think it has something to do with the strange uniforms that the French wore, well at least the boots...any ideas? I dont like going into class clueless!

To "Step your game up" means you need to do better. Or, in other words, put more effort into the action. He probably meant he needed to figure out what he was doing wrong and start doing it right.
