Quite the opposite. All adventure sports have their jargon. Climbers inhabit a mystery world of snargs, sprags and fingery cruxes. Surfers relish fat lips, hollow pits and gruftlebuckets. But these idioms express concepts not previously served by English.
Diving has a smokescreen for a language.
There is also a militaristic element at work here. AK in hand, in the DZ, then set off the TNT to destroy the VX missile base, it feels good to get out at the weekend and squeeze off a few rounds of acronyms.
