Fingerboarding, along with many other hobbies, has lots of jargon and special vocabulary associated with it.
If you are to become a true fingerboarder, you should have a basic understanding on most if not all fingerboard vocab.
To get you started, we have compiled a list of the most used words associated with Fingerboarding that you might not know:
The Fingerboard:
A fingerboard is essentially a shrunken down skateboard, so most skateboard vocabulary will also apply to fingerboards:
Deck: 
This is what you would call the body or the board of the fingerboard. On some cheap boards it is plastic, but on most it will be wood. It is what grip tape rests on and what the trucks connect to.
Nose and Tail: These are the front and back of the deck respectively. They are usually sloped upwards and symmetrical, but on some boards only the back tail be sloped and nose will be flat. They are what you use to get lift on the board to make it jump and perform tricks.
Grip tape:
This is a surface that sticks to the deck like tape. It is designed to allow you to grip the board more easily and better perform tricks. It is usually made out of smooth foam but can also be rough like sandpaper (the kind you would find on skateboards)
Hardware: These are the bolts that screw into the deck and connect it to the trucks.
Trucks: 
These are the pieces that hold the wheels and connect to the deck, made mostly out of metal or plastic. They allow the board to steer and come in sets of two, one for each pair of wheels. These are the three most important pieces:
Baseplate: Holds the truck to the deck
Bushings: Rubber rings that allow the hanger to maneuver fluidly
Hanger: Connects the wheels to the truck
Graphic: 
The image on the bottom of the deck. No real purpose except to customize the look of your Fingerboard.
Skateparks and Common Features:
This section is going to go over features and specifically skatepark features. Of course, we cant name every feature so these will be the most common ones.
Skatepark: 
A group of features designed to be skated on, such as ramps and rails. They are usually placed in a way that creates many lines to skate and maximize fun. Read more about them here.
Feature: Any thing that you can fingerboard or do a trick on. This can be anything, such as using soap bottles to grind on like rails or using dishes as a bowl. This also includes skatepark features like ramps, rails, and stairs.
Ramp: Something that you launch the fingerboard off of get more height rather than doing a ollie from the ground.
Rail:Usually a thin metal pipe, but can be described as anything you can grind off of, like the side of a wooden block.
Halfpipe: A ramp that curves at both ends and looks like a parabola from the side. Used for doing tricks off one end, riding down the ramp, riding off the other ramp while doing a trick, and repeating.
Quarter Pipe: A smaller halfpipe where the each side ramp has been cut in half horizontally. Used to get less air than a halfpipe.
Bowl: 
A hole usually set in the ground and is rounded at the edges, designed to ride around in it and do tricks off the side. usually circular or oval, but can also be found in any sort of shape with round edges.
Fingerboard Trick Variations:
Many fingerboarding tricks are just modified regular tricks. This section is designed to help understand what those modifiers mean. (All of this is right handed)
These can be very confusing, so familiarizing yourself with them is very important to becoming a good fingerboarder
Note: when riding the fingerboard backwards (left to right), remember that the nose and tail are now switched from when you are riding forwards (right to left)
Fakie: 
when you do a trick going backwards rather then forwards. for instance, if you usually move the board right to left, you would instead do the trick left to right while still performing it the same way if you were doing it regularly. (middle finger on the nose and index finger on the middle of the deck)
You are essentially just riding backwards with the same finger positioning as if you were riding forwards. For example, in a ollie you pop the board at the tail while moving forward (right to left) In a fakie ollie you pop the board at what is now the nose because you are moving backwards (left to right)
Varial: When you do a 180 while doing the trick in the opposite direction as you flick the board. For example, a varial kickflip is just a kickflip with a pop shuvit. in a kickflip you flick the board left while in the pop shuvit you rotate the board right (same as a BS kickflip).
Note: Only tricks that rotate the board sideways, such as a kickflip or heelflip, can be varial
Inward: When you do a 180 while doing a trick in the same direction as you flick the board. For example, a inward kickflip is just performing a kickflip and FS pop shuvit at the same time. In a kickflip you flick the board left while in a FS pop shuvit you rotate the board left as well. (same as a FS kickflip or hardflip)
Note: Only tricks that rotate the board sideways, such as a kickflip or heelflip, can be varial
Frontside (FS): This means that you rotate the board to the left. For example, a FS Pop Shuvit is just a pop shuvit rotated to the left rather than right.
Backside (BS): This means that you rotate the board to the right. For example, a BS Pop Shuvit is the same as a regular pop shuvit because in a pop shuvit you rotate the board to the right.
Nollie:
This means that you ride the board with your pointer finger on the nose and your middle finger on the middle of the deck. you still go forwards, but you pop the board at the nose instead of the tail.
For example, in a kickflip you pop the board at the tail with you middle finger while moving forwards. In a nollie kickflip you pop the board at the nose with you pointer finger while still moving forwards.
Note: The nollie is already a trick of its own, but when used as a variation of a existing trick (like a nollie kickflip) the rules above apply.
Switch: 
Riding switch means that you are riding backwards. This differs from a fakie because you have your pointer finger on what is now the tail and you index finger on the middle of the deck. you pop the board at the tail with your index finger while moving backwards (left to right).
For example, in a ollie you ride forwards and pop the board with you index finger on the tail. In a switch ollie you ride backwards and pop the board with your pointer finger on what is now the tail.
