A rarely observed mating ritual of homo sapiens from the Pacific North East. "The Pemberton Parachute" occurs when a female leaks or queefs male ejaculate and/or female "secretions" whilst asleep after a vigorous fudging. By the time of waking these various fluids have formed a cohesive bond in Satan's valley, swallowing, the entirety of the fitted sheet. Tired, but well rested from the previous nights fire hydrant jackhammering she leaps out of bed. This maneuver snaps the aforementioned fitted sheet from the mattress propelling the helpless woman out the window, fitted sheet, firmly attached in tow. It unfolds mid fall and thus safely, and embarrassingly returns the female to terra firma.
Meghan got a good shagging and had a good ol Pemberton Parachute eh?
