Derived from both a noun and a verb; poon and penetration. This explains when a male penetrates the vaginal front of a woman and begins sexual intercourse that penetrates rough. It cannot be used in an amateur setting due as a certain level of sexual experience is required to qualify for poonetration. The sexual activity can also be used with foreplay if the situation can apply.
"I'm about to start the long and winding road of poonetration on your sister tomorrow."
"I'm getting ready for the poonetration to begin!"
