Ex 1- An area in Southern California where the computer industry is booming and where most computers are either made, though of, etc...

Ex 2- A girl with extremely fake tits. Examples are that ho' Wendy Williams, Tara Reid, Pamela Anderson before the "reduction", etc. The girl's surgery is so obvious that her skin wrinkles around the implants and they don't move when she's pogoing or jumping at all.
Ex. 1- Lets go to Silicon Valley to get a job in the high tech field!

Ex. 2-

Dude 1- Yo check out that piece of ass, shes got such a tight ass and a fucking huge rack.

Dude 2- Yeah if her rack was real. Don't go near her dude. She's a typical sillicon valley man. I bet she could power the whole fucking country's computer network. Plus they probably feel like boulders.

(while Tommy Lee sucks on the girl's nerps as onlookers watch in horror)

12.
An area in northern california that is heavily populated by computer and technology related companies. This area is devoid of females and filled mostly with fat ugly bitches with attitudes who expect to marry a millionaire. On the other hand, there is an abundance of social skill deprived males who repeatedly wank off to animted internet porn and could never get laid with a real chick. Bin Laden should set this place on fire, not New York.
God, holy crap, all I see in San Jose is a bunch of useless geeks and chicks who look like they are from Mars.
