When your GPS hasn't been updated and tells you to take a turn on an imaginary road. The GPS is basically making guesses on where to turn just to get you back onto roads that are in the system.
I got lost trying to find my way to the reunion. My GPS kept telling me to turn right off of the bridge. The problem was there was no right turn and I would've ended up in the river. It wasn't doing a good job of giving me directions. It was just giving me a GPGuess.
