When using a mobile phone with GPS services and participating in a location aware social network on your phone and sharing your location information with the network, the Ghost Lōc (pronounced "loke") is your true location shared only with your close friends. While, your GPS Cloak broadcasts a fake location to the rest of your social network.
Husband and Wife are both on a "location aware" social network for Blackberry Storm mobile phones so they can know where each other are at all times. One Sunday morning, Husband tells his Wife he is going to the office. He enters the office address into his GPS Cloak. Husband really goes to the Ghost Lōc which is the golf course. And all the while, his Wife thinks he is at the office because that is where his GPS says he is according to the social network (or phone tracking website)!
