A signature dance move to be performed at any and every occasion where a dance floor is made available (i.e. weddings, brisks, funerals, etc). The hands are put up and waved back and forth similar to windshield wipers.
Dude! Dynamite just came on the radio! Do the windshield wiper!
Awww man! Look at that hot chick by the wedding cake doing the windshield wiper.
When a woman is wearing glasses while giving you oral pleasure, she pulls your member out of her hot mouth and begins wiping it back and forth across her spectacles while you "NUT" joyously. Thus immitating the windshield wash and wiping actions.
Dude, tom and suzie were doing 69 when she gave herself the windshield wiper.
