The phenomenon in which a normal conversation turns blue, becoming so riddled with sexual innuendo that it's rendered nearly impossible to steer back in a non-pervy direction. Every innocent comment starts to become a dirty double entendre, until eventually the entire conversation turns into a complete smut-fest from which there is no return.
Girl: Ah, who doesn't love stripper zombies in Portland? That'd go down like Jesus on a velociraptor.

Guy: I have to admit, when I first read 'go down'... I had rather blasphemous thoughts.

~ten minutes later, during which this term is invented~

Girl: Hmm, this Urban Dictionary thing is quite fun. Something for the annals of history.

Guy: Two n's - one 'n' is bad.

Girl: Yeah, I always thought that 'annals' was an odd word.
It really could so very easily be another.

Guy: Terribly easily. So, how is the entry? ...Oh, Jesus!!!!

It's the future of sex. Sex with hot robots. They feel surprisingly soft, but can turn tough and durable during battle mode. It's based on smart metal. It's a metal that's already under development, but will be fully developed in the future. It's a metal that can change material properties at will(they could get soft, smooth and squishy like normal or wet human body tissue, but get tough like steel during dangerous situations and battling). Girl sex bots. Sex-bots.
Dude 1: I like Jenny XJ9.
Dude 2: Well. Once you go metal you won't want to settle!
