Ass spider 

A little piece of dried poop, which, when pulled loose, takes along with it a collection of butt hairs so it resembles a spider body and hair legs.

It's a guy thing. Women do not have ass spiders.

When he pulled the crusty bit loose it ripped out a bunch of butt hairs leaving him holding a worthy ass spider in the paper.

Spiderman Ass

The act of laying on the back on a flat surface preferably the ground so that the anal region is pointing toward the target human. The human in which is committing the act will then roll his or her undergarments cinematically upward slowly to at last reveal their entire anal region to the target in the same fashion spiderman rolls down his mask in the Spiderman kissing scene with MJ. (prefered to be done with spiderman boxers)

I proudly presented my spiderman ass to mary jane as she stared shockingly into my hairy brown eye.
