n.
Sport of sliding down a snow-covered hill on a toboggan, a long, flat-bottomed sled made of thin boards curved up at the front end.
The word is of Algonquian origin and probably refers to a towing sled. Tobogganing as a sport appears to have originated on the slopes of Mount Royal in Montreal in the late 19th century. In the early 20th century many tobogganing chutes (3-ft-wide wood-or ice-sided channels) were built.
