bike-wacking
v.— «Unfortunately, water levels created a washout that changed the face of that trail and left us what is affectionately known as “bike-wacking.” This is similar to “bush-wacking,” but involves not only trying to drag oneself through thick branches and undergrowth, but also an unruly bike in a constant tangle with said undergrowth.» —“A Golden time with very little sleep” by Shawn Wenger Kamloops This Week (British Columbia, Canada) July 29, 2007.
