If it helps at all FS means Front side and BS means Back side
If its grinding then BS is if you are approaching the grind with your back facing it. If its FS then its in front of you
If its rotation FS would be if you did a 180 degree spin spinning into your forward shoulder (Goofy = Spinning Clockwide / Regular = Spinning anti clockwide) If its a BS rotation you will start by spinning into your back shoulder. (Goofy = Spinning anti clockwise / Regulary = Spinning clockwise)
Then theres things like pop shuvits and normal shuvits. A FS pop shuvit would be you popping the board in front of you and a BS would be you popping the board behind you.
Grabs: Simple really FS grabbing the side of the board by your toes, BS grabbing the board on the side by your heels.
Inverts: Same as grinds but on the lip of a halfpipe.
Theres probably more but there all the ones i can think of.
Fs (frontside) is your facing the direction your moving while doing the slide, Bs (backside) is the opposite.

I would say there is 20 usual tricks. Here is the list of all tricks as a real bodyboarder : # Take off # Spin 360° # Reverse spin 360° # Cut-Back # Cut-back 360° # Reverse 360° Cut Back # El Rollo # Air Rollo # Invert Air # Projected Air # Roll spin # Air Roll Spinner (ARS) # Back flip # Gorf # Reverse rollo # Reverse Air # Air spin 360° # Reverse 720° # Frontflip # Barrel / Tube You could add Combo moves : # Take-off 360° # Take-Off Reverse # Inverted Air to Reverse Air # Double Rollo # Inverted air to roll spin # Spin 360 to rollo (Kyle maligro was really good at that one) # Rollo to frontflip # ... I am not listing what I have never seen. All these tricks are available on video
To transfer elevations, BM + BS = HI - FS = Elevation BM - Benchmark BS - Backsight, or a measurement taken on a benchmark HI - height of the instrument FS - Foresight, or a measurement taken on an unknown point
To calculate the reduced level in rise and fall method, you need to add the height of instrument (HI) to the back sight (BS) if the instrument was set-up on the point, or subtract the foresight (FS) if the instrument is sighted on a new point. The reduced level (RL) is then given by RL = HI ± (BS - FS).
Asians get As Bs Cs Ds or Fs just like the rest of the humans.

there is no easy way to grind, some grinds are easier than others like FS and BS boardslide as you don't have to do much apart from get on and off the rail
is a fs 2 starter comparable to fs 22
4.0 grade scale is 0.0 for F, 1.0 for D, 2.0 for C, 3.0 for B and 4.0 for A. All As, Bs, Cs, Ds and Fs weight the same.
