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!

An addendum to the method of performing the Spiderman below. 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).
