What is Uber-jack? What does mean to be Uberjacked?
The Guru Take
It's a slang for when someone else takes your Uber ride.
Uberjacking or Uber-jacking is a slang term that refers to when one assumes the identity of someone else and takes his or her Uber ride, hence not having to pay for the ride. This is a common practice in busy situations and is often difficult to catch.
If you have an experience of your Uber driver not showing up and starting a ride without you, it's possible that your Uber drive was hijacked or "uberjacked."
