Girlfriend Positioning System 

The surreptitious use of Google Latitude on your girlfriend's phone so that you can track her whereabouts without her knowing. Tends not to work with technology-proficient girlfriends. Also requires a phone that supports Latitude, but helped by the prevalence of Android, Apple OS and Blackberry phones.

Commonly abbreviated GiPS (pronounced: jips).

John: so Carla's gone out with her friends tonight, huh? Where are they headed?

Bob: she said Misty's but, hang on - my girlfriend positioning system shows an anomaly - why is she in some random street in Hangleton???

John: dude!
