When you are banging a chick from behind, you cum in your hand and spit on her anus, thus making her think you have ejaculated on her, when she turns around you throw that shit at her in a spiderman-esque fashion.

A Spiderman is when a guy cums in his hand then flings it onto his partner's face just like Spiderman shoots his web. (Original)

The act of jerking off into your hand and then throwing it at your friend's face who has passed out at a party. You must yell "web barrage" as you fling your jism at his face and than yank your hand in backwards motion, just like spidey. The act is considered borderline gay due to the symbolism. (Webbing a dude and pulling him towards you = you secretly want him)
Yoo Chris passed out... you were talking about spidermanning all day yesterday. Let's go bro, let the jism fly. With great power, cums great responsibility!
