Generally attributed to whitewater kayaking afficionados in the eastern United States in the mid- to late-1970s. The term derives from the onomatopoetic sound that a kayak makes when it lands on the water after “ski jumping” the waterfall forming the backwash.


boof ‎(plural boofs)

  1. The method by which kayakers “jump” hydraulic backwash, known as holes or hydraulic jumps, in high-gradient mountain rivers. The action is analogous to a skier jumping a cliff.
