Paintball Terms! And heres something I thought I might want to add on for ya.
PAINTBALL TERMS!:
FPO-Field Paint only
BYOP- Bring your own paint
Cocker- Auto-cocker, a type of paintball marker
Trix- Matrix, paintball marker
Timmy- Intimidator, paintball marker
Impy- Impulse, paintball marker
Semi- Semi-automatic, or a large truck, eh either works to get the enemy
Paint- Paintballs, the things you fire
Bunkers- Usually a forested area, though sometimes open where you battle among giant pieces of wood and doors and stuff as if they were a bunker
Bunker'd- Jumping over a bunker and splatting the guy that has been annoying you for the past hour behind a bunker
Bunker(after popular demand)- An obstacle used to hide behind, usually wood, or doors or tires or something similar.
Splatting, Killing, Painting- Hitting someone
Hand signs-I suggest you and the people you will work with put together a system of hand signs so that everyone understands whats going on, also yelling has its disadvantages apparantly some peopel have good ears(I have a few welts to prove it)
Rush- Just like it sounds, everyone sticks together and runs at a fortification firing rapidly at anything that moves, usually you either die or take the fortification, or retreat.
C02- Most times the type of gas your using, Carbon Dioxide, we could get technical and into the chemistry but thats really all you need to know
Nitro- They used to use Nitrogen to fill the tanks, but have since turned to Compressed air instead, its much more consistent and is used by the higher end guns(mine can't use C02), the tanks are usually very large and measured by cubic inches and PSI\/ , I currently fire a 4500/68 (which is 4500 PSI and 68 Cubic Inches, ci)
PSI- A Way to measure gases, usually only referred to between two types of Nitro tanks
PMI- A company that makes paint and paintball guns
Walk-on Players- Usually experienced players that play regularly but don't play with a specific group, they show up or call ahead as a small group of usually 1-7, sometimes they are welcome sometimes they aren't, usually you might want them on your team
SpeedBall/Hyperball- A smaller faster paced course. Its usually in the open and playing around a few obstacles you jump on around and in to get to the enemy, these games are faster paced and don't require as much strategy but do need a lot of moving speed and agility to play
Forest- Usually playing, well, in the forest, usually something like bunkers or fort
Fort, alamo, take the fort- One team is in the fort one is on the outside, one wants to take the fort the other wants to keep it, usually a time limit, usually the players on the outside outnumber the fort slightly, grenades are a fun tool

Concept fields- New types of fields including speedball, hyperball and some other fun ones
Air compressor- Whats used to compress air into the C02 or nitro tanks
Enemy- Shoot him
Ally- Please don't shoot him, I remember a few fun games were I was attacking the other team then found they were on all sides, oh wait a min that was my team! Try to know where your guys are, most times if the group is too big to remember they have bandanas or arm bands of some kind
CTF, Capture the flag- Simple, you have a flag, they have a flag, you want theirs before they get yours.
Mask- The thing on your face, they come in many diferent shapes and sizes usually with goggles built in, some come with anti-fog some without, some you add in
Hopper- The giant black thingy that sticks up out of your gun, it usually holds paint and a good amount of rounds, try to keep it secure and always make sure its fastened down, dumping out your paint is not fun, also there are mechanical and diferent sizes but most times people stick with a 250-500 holder
Elbow- What connects the Hopper to the gun, on straight feeds the hopper just slips into the gun
Hopper-full- The amount of paint usually in a hopper, if someone says you wasted it it isn't a nice remark, sometimes its just a statement so don't automatically jump on em.
Pop&Shoot- Usually in bunkers, Pop up and shoot, sometimes you do this to cover another player
Snap Shooting- Usually the same as above, but much quicker and used to try to hit someone while remaining unscathed
Cover fire- Fire off a medium amount of ammo just to get the other team to duck away from it so your teammate can slip up into a further forward stronghold
Musket Ball- Usually used as a quick fun game where you want to waste paint at the end of the day, everyone stands in a line like in the Civil war and you fire and keep firing
Overkill- Shooting a player multiple times after he/she has already been killed
The gauntlet- Usually implemented by referee's if someone does something bad, they take your gun stand in a line and tell you to run, and they don't stop firing anytime soon
Goggles down- You must keep yuor goggles down, safety rule
Barrel plug- A plug you put into yuor barrel, required by most fields also can use a barrel condom instead on some fields
Barrel Condom, cover- A small cover that goesover yuor barrel while a rope or string fastens to the end of the gun making it impossible to fire, can use instead of a plug on some fields.
Velocity- How fast yuor rounds will fire, usually the only comment on this is if its too high or low, a high velocity really hurts, and a low can barely make it out of the barrel, most times you can ask on a field if they can do a reader on your gun and measure the velocity, you can adjust this with a screw driver or a small knob at the end of yuor gun
Marballized Paintballs- *shudders* this really really hurts, some players like them but you don't want to get hit with them, they are harder than regular paintballs
Stocks- Most stocks go onto the gun at some point in the gas system and go back into yuor shoulder for support and aim
Scopes- Simple, a scope, like on a rifle
Right/left flank- The right or left side of your team, or sometimes will be yelled if they need assistance or wish to flank the other team by putting pressure more on side than another.
Surrender- Usually called surrender, when you get within a certain amount of feet and yell at the other team to give up, most times they will because at that range it hurts not to
Drop Downs/boxes- Customization to the C02 N02 input valve thingy to allow you to move the canister out of yuor way or out of the enemies fire
Blind firing- When yuo take yuor gun and put it around the bunker or obstacle and fire without looking, illegal in most fields, also can be if you pop up and fire at anything you feel like firing at
Long-balling- Firing at a great distance,but usually out of your guns range and using the arc of the paintball to yuor advantage usually requires you to fire more than a few shots.
Camo- Camouflage, most people wear this to break up their outline
E-anything- usually just means its electric in some idea and is assisting them.
Expansion chamber- A chamber that usually also has a grip that works on bottom line guns that allows you to spend more C02 out of the same amount
Gas-thru-grip- Usually like an expansion chamber but it doesn't help yuor C02 usage at all, it just gives you someting to grip on bottom line guns
Bottomline guns- Usually a gun where the hose goes from the barrel to the bottom of the handle and ends in a valve for the tank
12 oz. 20 oz. etc.- The size of the canister of C02
Chamber- where the gas is released pushing the PB out
Barrel- Usually you start with a stock(regular) one but you can buy customs that increase your range and can add a spiral onto the PB, some stock barrels have spirals already
Ball hauler- Usually just some form of belt or pack that allows you to carry more paint within small tubes, also can be the person with the most of them on, call him to get a little refil

Oil- Usually you might want to add a special PB oil to yuor guns or onto parts of it to keep it working and in good shape, sometiems helps with C02 fastening problems too, or at least it does on mine, try to add some each time you fasten the c02 on to get the oil pushed thorugh the parts

O-rings- A Small ring of plastic or rubber that is put at the end of yuor c02 or N02 tank, when inserted into your gun, the ring expands allowing the gun to not leak, many times if your leaking you need a new o-ring, keep a few of these around

Headshot- Head shot,

try to get a lot of these
Transport- The guy or girl giving you a ride home and back, try to go easy on them

Viewloader- Usually a brand of hopper and carrying case that allows you to see through the top of the tube or hopper
Red paint- not really a term but I wanted to add in that some fields don't allow red paint, be careful
Safety- the litlte button on your gun, keeps you from firing but most fields require it and a plug or condom for safet, red is fire, black is good
Safety rules- You may walk on the field and hear safety rules and zone out but pay attention, they will not screw around with you on this, they will kick you off if you put someones vision or life in danger. Sometimes theres rules they follow but noone else does, pay attention! They will be serious, you don't have to be totally serious but don't be a total jackass.
The best- Usually talking about me
