spiderwanking 

When you spend far too much time detailing a technical drawing. When a drawing can be produced with significant detail to carry out the manufacture but instead 3 days is spent highly detailing the drawing. By J.A.K. Baljaffray, Glasgow

You have been spiderwanking meaning you have spent far to much time and effort on a job over complicating it eg when drawing a section of steelwork you spend time embossing the steel with letters and numbers in a model

spidermanning 

To do your girl doggy so she cant see you then pull out just before cumming and cum in your hand, call your girls name then unleash your jiz onto her face in the same way spiderman spins a web.

I enjoyed spidermanning your wife last night, she seemed as surpised as you do right now.

spidertasking 

like multitasking, but with a minimum of 6 tasks going on at any one time.

Man: "oh yeah I'm pretty busy, gets a bit much working on so many things at the same time."
Woman: "oh yeah, women are much better at multitasking than men"
Man: "uh, yeah look, I can multitask with the best of them, but spidertasking is a whole other world entirely."

Spidermanning 

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!
