One of my other obsess^H^H^H^H pass times is archery, where there are a number of different disciplines. In recent years technology has improved the humble stick and string into a technological marvel, and at some point a slightly deranged man (probably) decided to had pulleys to gain mechanical advantage. The new fangled contraptions have evolved into very high tech devices capable of shooting arrows at over 350 feet per second (Its a leftpondian dominated sport) and are way more accurate than even the carbon fibre reinforced stick and kevlar string I use. We, in the archery world refer to the users of these devices of Satan as Dark Siders, and the whole of Compound (for that is it's official monicker) archery as the Dark Side.
In comparing the two sports (that of cycling and that of archery) it can be seen that these new fangled contraptions, the Recumbent cycle and the Compound bow, started to become popular in the eighties (yes, I know the velocar is older) and both were viewed with some suspicion by the incumbent population. Both were seen as as subversive to the main cultures they were in, and so by association with subversion, became cool. Youth likes cool. Youth also liked Star-wars in the eighties, and wanting to be seen as uber cool, and because the main stream viewed them as heathens, Youth decided to adopt the Dark Side as a title for their sub-culture. Youth, being a bit lacking in the experience field, also thought they were being unique and witty. Youth never learns
