The Spiderman is a relatively unknown sexual move. A guy will ejaculate into his hand, then sling his semen at a target with his pinkie and pointer finger extended, a la' Spiderman's signature hand motion. If one happens to "sling his web" at a person, it is entirely appropriate to scream "YOU KILLED MY UNCLE, BITCH!"
Jarred walked in on me masturbating last week, so I chased him down and did the Spiderman right on his back.
