Bushwhacking is the abrupt removal of one's pubic hair. While commonly confused with the more frequently used terms "brazilian wax" or "bald eagle," the term bushwhacking is generally preferred when whackee formerly sported a lowfro or buckwheat type of 70s pubic coiffure, and does not always denote complete baldness. The sudden and abrupt removal of such luxurious nethercarpeting conjures up images of Indiana Jones, sweating profusely as he slashes his way through a dense jungle with nothing but a machete and an enviable suntan.
