I'll give you a real response. First off, find a good location to learn. A cat track is a perfect location, or any sort of flat snow transitioning into a downward slope. Knuckles of jumps are a good spot because you can come in really hot and take your nose butter deep down the landing. Make sure your DIN is high enough so that your bindings won't explode and leave you face-down in the snow.
Approach your drop with your weight forward, and your shings pressed into the front of your boots. Pivot 180 degrees on the front of your skis. Try to have nothing but your noses on the snow at this point, with your body pressing into your skis. Example:
This is where you need to POP. Keep turning your head - look for your landing and your body will follow. Once you land a 3, try to add some rotation. Nose butter 540's are really dope and aren't that much harder.
