The term 'Biverwhacking' is derived from the original meaning of 'building a wooden hut from natural resources'.
When applied in a sexual sense, however, the meaning changes. It becomes an appropriate way of describing sexual intercourse using oak implements.
These implements are generally freshly cut oak branches/twigs. Although this is the case, the rarity of the material means it is harder to source. Therefore it is becoming more popular to use commonly known trees that are widely available, such as Pine, and reuse them - to be more eco friendly.

We got so loaded on the trail that we had to camp out, but J.R. had forgotten his bag, so he asked if he could BivyWack with someone.
