Before you try this you should know how to Half-Cab, Crooked grind and you should probably learn Half-Cab to Nose slide before you learn this.
Come up to your target Fakie, be parallel to it and then start turning and pop a Half-Cab. Spin around and once you see your target setup for a crooked. It's good to setup in the air, like keep your front foot on the nose so when you land you can already have your weight there. After you land start grinding across, it's easy to get stuck when you land in the crooked grind so try to lean back to make sure that doesn't happen. Once your grinding the rest is simple. Just choose if you want Switch out, Regular out or a shove out and just do it.
Good Luck!
