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'
