Spiderism 

The polytheistic religion based on the group and teachings of the Spider Gang, or its beliefs and practices. One must support the beliefs of the gang in order to be accepted as a Spiderist. Places of worship include, but are not limited to; the basement and the streets. Practices of this religion involve doing drugs, listening to the gangs music, participating in fanart friday, and placing cards against humanity boxes in children’s aisles.

Soon after I found out about Spider Gang and their ear rape penis music, I started to believe in Spiderism.

Spidering

Similar to doggy style positiong but involving anal penetration. The guy gets right ontop of the girl with his legs on the inside of hers. Limb order from front: girls arms, guys arms, guys legs, girls legs. This produces the 8-legged effect.

At the point of ejaculation the guy pulls out and cums all over the bed in a wide spray pattern creating a 'web'. The couple then collapse onto it and sleep in the 'web'

Spidering

Ezz: I can't believe we slept in your cum last night
Chris: Thats what happens when you've been spidering, the web was cosy wasn't it!

spidering

When a guy cums in his hand, and shoves it up the woman's vagina. This is what spiders do when they mate.

Dude: I came before I could get it in, so all she got was a spidering.
