1 - When a girl is going down on you, and just before you climax you pull out of her mouth and nut in your own hand. Then fling the jism in her face, as you jump to your feet, making sure to properly mimic Spidey's web slinging hand motions. Now stand in a position of bravery, and power like any superhero would. Be sure not to react when she yells at you. Stand tall and proud, not too many guys get the chance to do that these days.
Yeah so i nutted in my hand... And i was all like "PLAH SPIDERMAN!!!" And then she was all like "WHAT THE...?" And i was all like... "shhhh baby, the games back on."
2 - An addendum to the method of performing the Spiderman above. When completing the Spiderman (flinging the "web" into the girl's face), you must make the appropriate Spiderman hand gesture AND voice Spidey's famous web noise - THWIPP! Immediately web swinging away is recommended (for added effect throw in a Spidey catch phrase or witicism).
OH OH YEAH! AHHHHH....... THWIPP!!!! ....Cripes!
3 - The act of jizzing in your hand after pulling out and then throwing it in your partner's eye.
Girl 1: Why are your eyes all red and swollen?
Girl 2: My boyfriend spiderman'd me last night.
