Ollies: Ollies are a type of jump. You lean on your back foot and pull your front foot into the air. Once your front foot is in the air, push your back foot off the ground so that you are in mid-air.
Snowboard Ollie
Tick Tack: If you know how revert on a skateboard this should be easy. Lean on your back foot and pull your front foot in the air. Slide the font of your board to right while it is in the air and then put it back on the ground. Do the same, but instead slide your foot to left. Repeat left, right, left, right, left, right, left, right as long as you want to.
offcourse thats a wrong imagae :D
This Thingy: I'm not sure if this has a name. You lean back like you're turning, but do it really fast until it like you are going to stop. As you are doing this your back foot should slightly be digging into the snow. This will make snow fly everywhere. In new, fluffy snow there will be a whole cloud of snow around you.
180: To start you either need to Ollie or just jump. twist your body in mid-air making your snowboard spin. You should land switch. Landing sideways isn't a good idea. Make sure that either land level or on your back foot. ( the video is cheesy and lame, but it shows you the basics)
