The act of keeping your dick hard when in the process of masturbating (burning one off). Accomplished by cupping your hand and letting your fingers hang resembling that of a spider and stroking the head up and down with your fingertips. AKA The Spider
When you are in the restroom and someone comes in and you were masturbating. In order to keep your dick hard (quietly) until they leave, you would use the spider.
