hoover

v. tr.; While engaged in sexual congress with another person in either the prone or animalian (see: "on all fours," slang) position(s), the act of simultaneously displacing the recipient of the sex act's front appendages, or that which at the time of execution is bearing the forward weight of said recipient, via a swift kick or otherwise effective movement, thus forcibly causing the upper torso and head of said recipient to fall to the ground, and raising the hindquarters, leaving said recipient in a partially inverted position. Following this, the sex act's performer seeks to manoeuvre the recipient around the immediate environment in a fashion similar to that of a Hoover vacuum sweeper.
