Niche
group of idiots who enjoy strapping themselves to planks of wood, and hanging on too a piece of rope off the back of a high-end race boat to compete through an
imaginary race track made out of floating buoys.
Commonly found repairing not helping their team prepare their boat, putting enough tape on their feet to kidnap a concert, and drinking way too much before they're meant to race.
Evidence :
Experience ;)
