Etymology 1Edit

Generally attributed to whitewater kayaking aficionados 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. A “jump” over hydraulic backwash in a high-gradient mountain river, an action analogous to a skier jumping a cliff.


boof (third-person singular simple present boofs, present participle boofing, simple past and past participle boofed)

  1. To make a jump like this when whitewater kayaking.
