Lycra is an odd stretchy material that occasionally is made into
clothing, especially shorts.
Wearers of lycra are usually involved in sporting pursuits such as
cycling or athletics. People who wear lycra have to be thin, quite insane,
and happy to show the outline of their genitalia to anyone they may
encounter.
For these reasons the wearers of lycra are usually found accompanied by
other wearers of lycra in forests, moors and remote areas, where they can
expect to meet no one except Horse Riders wearing jodphurs1,
an even more eccentric item of clothing.
1 A type of legwear named after Jodhpur, a city in Rajasthan in north-west India where jodhpurs are hardly worn any more.
