How to Do a B/S Slappy
Here is a “How-To” I wrote for a b/s slappy. The principle is basically the same for f/s, the mechanics are just slightly different.
(1) Find a tiny curb. We are talking REAL small here. 1” – 2”. No higher than two inches. If possible, find a slanted one (like they have in California). If you can’t find a slanted one, no worries. Just make sure the one you found is 2” tall or shorter.
(2) Wax the fuck out of that curb.
(3) Go to an empty part of a parking lot. Once you are there, tighten the fuck out of your trucks. Yes, I said tighten your trucks. Stay with me on this one.
(4) Do some backside carves, really flexing those ankles, and pointing those toes down. Your trucks should be so tight now that both your heel-side wheels lift up in the air. You should be carving on just your two toe side wheels. Do this a bunch so that you can easily go up on to your toe side wheels whenever you want.
(5) Loosen your trucks up again. Get them back to where you had them before.
(6) Go back over to that tiny curb. Approach the curb at about a 45-degree angle, with a decent speed. Have your weight slightly ahead of your feet. Knees bent/and crouching down a tad.
(7) Just as your front heel side wheel is about to slam into the curb, do that same motion you did with the really tight trucks to carve up onto two wheels. Shift/thrust your hips toward the front of the board, so that they “catch up” with your shoulders (which were slightly ahead of your hips/feet), as your do this, also swing your back leg around (almost as if front leg was the pivot point) to help get the back trucks up on the curb. MAKE SURE that your shoulders stays in a parallel line directly over the curb. If your shoulders are too “open” (not parallel) it is MUCH harder to get your back truck on top of the curb. There is a LOT going on here, all at once, and they are very subtle motions. Getting the weight distribution, weight shift, speed, angle, and shoulders to all go as one, I think, is one of the reasons slappies are literally the HARDEST tricks to teach.
(8) Once up there, grind away until you want to come off.
(9) Find a SLIGHTLY taller curb, and repeat the same process.
Note: The textbook definition of a slappy makes NO USE of the tail to lift the front truck onto the curb, and NO USE of the nose to lift the back truck up, either.
Note on F/S Slappies: On f/s slappies, the shoulders are SUPER important. Not to scare you, but f/s slappies can produce some NASTY slams. What often happens is those slams is this sequence of events: (1) you get the front truck up, but the back truck doesn't make it, (2) the rear toe side wheels bounce off the curb, (3) the back end of your board then slides around, turning the board 90 degrees (e.g. board goes into a f/s railside position), (4) rear truck then catch against the curb and board stops dead, (5) since your feet are now twisted a bit under your torso, it is next to impossible to "run out" of, (6) This sends you flying backwards toward your hip/back/forward elbow. Slams like this are bad enough on flat ground, but now you also have the edge of a curb to look out for. Making sure that rear shoulder gets parallel with the curb, when "slapping" into it, can help avoid this sequence of events. Leaving the rear shoulder "open" is almost an invitation for this type of the slam.
Note on Wheels Size & Shape: Larger wheels make it easier to roll over/slap-up a curb. Wheels with a more rounded profile (e.g. Spitfire Classic type shape) make slappies easier than a more squared-off shape (e.g. Spitfire tablets).
