controlled falling down a hill, dressed up as a winter sport for the brave and bored.

means The act of sliding down a snow-covered slope on a long, flat-bottomed sled with a curled-up front.

from From 'toboggan,' which English borrowed in the 19th century from Canadian French 'tabaganne,' itself taken from a word in the Algonquian languages — Mi'kmaq 'topaqan' or a close relative — naming the sled used to haul loads over snow. The word rode south with the snow it described.

viking origins: word comes from the Algonquian people, not Scandinavia
olympic cousin: luge descends from recreational sledding at terrifying speeds
speed feat: toboggans can hit over 60 miles per hour
no brakes: steering relies entirely on body weight and prayer
ancient transport: originally used to haul goods across frozen ground
