A sexual display wherein a male gyrates his pelvis so that his flaccid penis whirls in a radial manner like the blades of a helicopter. Such a display is often used to impress a female or females before a sexual act.
Jane was uncertain as to whether she would allow John to perform the act of vaginal penetration until he used his helicopter dick maneuver, then she readily succumbed.
