One of evolution's greatest success stories. There are spiders all over the world, and the oldest known fossil spider is 380 million years old. Spiders are eight-legged and carnivorous, use silk in a variety of ways depending on the species. Many spin cobwebs to catch prey, larger spiders line the edge of their burrows with web. The bolas spider is named because it throws a line of web ending in a sticky lump to catch prey. Spiders inspire fear and revulsion, quite undeserved, but probably not helped by years of movies telling us spiders are humanity's enemies. Schools are not much more helpful. I still remember a science teacher telling us a black widow was the size of a human hand, which is rubbish. There are some dangerously venomous spiders, like widow spiders, funnelweb spiders, brown recluse spiders and brazilian wandering spiders, but they are a tiny minority of the huge number of spiders in the world. Just to drag some widely-held beliefs into the light of reality:
1: Spiders are not watching you. Most, apart from some jumping spiders, have very poor eyesight.
2: Spiders do not come out of plug-holes. A spider in the bath has fallen down there and can't get out due to the bath's slippery sides.
3: Large hairy spiders are not automatically dangerous. In fact nobody has ever died from a tarantula bite.
4: Women are not automatically scared of spiders. In fact most of the calls the British Tarantula Society gets regarding fear of spiders are from worried men.
Hysterical person: Help! I saw a spider! I'm not going to bed! It might be there waiting for me!
Other person: What makes you think any self-respecting spiders would want to get into your bed?

1. Predatory arachnid that usually has silk-spinning organs at the back end of the body; they spin silk to make cocoons for eggs or traps for prey
2. A computer program that prowls the internet looking for publicly accessible resources that can be added to a database; the database can then be searched with a search engine
3. A skillet made of cast iron

A spider, aka arachnid, is an eight-legged creature of doom. Humans eat eight of them a year in their sleep. Matt Bellamy has stated his wish that gravity on earth were less so that they would all die. Then again, he also said we were derived from them. Not the most reliable source.

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

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.

When your fisting someone and your hand is in their ass, you spread out your fingers as wide as you can and yell: SPIDER!!!
...and that was the last time I gave someone the spider before cutting my finger nails.
