When a man gets an erection places his thumb and index finger around the base of his unit and swings it around like the blades of a helicopter. The boner copter is very versatile and can be used for any number of purposes which include :air fan, bagel cutter, drink mixer and is now being used as an acceptable method of transportation.
Sally says to her husband:"Hey honey, its really hot over here, can you come over and give me a boner copter?"
