when someone is on their laptop at school, coffee shops, or book stores and other people can't help but look at what they are doing.
Dude you should be taking notes and not spy-fing on the girl in front of you.

spy-fi is just wi-fi, or wireless internet, that is obtained from a location other than the place you are currently at. Example: Staying in a hotel, and successfully connecting to a wi-fi network at a nearby restaurant, cafe or other place where wi-fi is readily available.
Bro, I couldnt get wi-fi here at the hotel, so I resorted to spy-fi from the starbucks.
