The act fucking a girl doggie style, spitting on her back just before you are about to bust, and when she turns around, busting in her eye with your hand stretched out like spiderman. For this to be 100 percent effective, you must yell, "Spidaman!"
Dude 1: Dude, why can't she see out of her left eye anymore?
Dude 2: Spidaman!
