The concept is not new, but the name is (and probably will continue to be as it isn't something i'd pick up on) I stopped worrying when, after perhaps a decade of the inert life style featuring 2 liters o' moutain dew and bats o' cheetos, i got it in my mind at like 1 or 2am to do a crazy solo hike the next day, made use of every available bit of daylight, but completed a mildly ambitious circuit with no more issues that slow going, naps at summits, and side stepping a moose. i got back to the car at the same time as another pair o' hikers i'd met at the summit, and seeing the occupants of both cars at the trailhead parking accounted for, the state police cruiser moved on. That was a few years back, so perhaps i'm due another test to verify, but i'm sure i'm fine and remember the first rule, bein' that getting back is always more important than getting there. But yeah, my gut is suspenders worthy...
