hitch a lift
1. To hitchhike. (Done by putting one's hitch in the air in order to signal passing cars that one is looking for a ride.) I spent the summer hitching lifts along the west coast. We didn't have any money for a taxi, so we had to hitch a life home.
2. To be driven to a location in someone else's car. A: "Do you need me to drive you to the movie?" B: "No, I'm hitching a lift with Janet."
