Sillicone Valley 

The area of Draper, UT where all the sugar mamas have plastic EEE jugs.

Connor's mom LaCherity offered me her body, but I was like "Hell no, I ain't taking no plastic sillicone valley bitch!"

Silicone Valley 

Nickname for the San Fernando Valley in California, known for having a lot of porn studios.

I moved to the Silicone Valley with my rubber tits to pursue a career as a porn star. After starring in over 200 creampie gangbangs, I upgraded my tits and ass from rubber to Silicone. I get even more, and higher quality, dicks in my pussy.
