Skydiving is a sport with a very prominent culture and language.
Although far from complete, here is a short glossary that should be able to explain some of the terminology. Many people think of skydiving as something completely dreadful, something that they would never ever do, not even if they lived to be a thousand years old. The idea of falling from an altitude that guarantees a certain death is a terrifying one - this fear is in fact carried through our genetic code. Most of us human beings are afraid of heights - even if this fear is not always obvious on the outside, it is still measurable. Adrenaline is being released, the palms start to sweat, the breathing frequency increases and the heart starts pounding faster.
