In a March 21, 2016 Wall Street Journal article about hiking the Appalachian Trail, I was entertained by the nicknames (or trail names) hikers used to identify themselves in trail log books.
Examples were Doc, Sunshine, Turtle, Moose, and Strider. This made me wonder just how these names came to be attached to a particular hiker. I found one example: A hiker slipped in a stream and got wet. He stood close to the campfire to dry out. His pants began to steam as the water evaporated. Thus he gained the trail name “Hot Pants.”
