The self-given name of any person tramping via foot, bike, or car. Creation of the name usually signifies someone entering a new stage of their life and leaving behind the previous one, at least for a time. A famous example of a road name was Christopher Johnson McCandless's road name "Alexander Supertramp."
Person 1: I'm going to start huffing it.
Person 2: Are you going to give yourself a road name?
Person 1: Yeah, I'm changing my name from Jessica to Gaia so I can truly leave behind this life of materialism.
Person 2: Good for you!
