Another name for a hidden shortcut in a forest/city/cave/race track/etc that for the longest time lays undiscovered, but once someone finds it, word gets around and everyone will try to use it as well, with varying levels of success.

The name comes from a fabled exploit in Mario Kart 64, when playing Rainbow Road, turn and jump just as you start down the first ramp, and if done right, you'll skip a huge portion of the track
Guy 1: There's gotta be a faster way out of this forest!
Guy 2: Follow me, there's a double R jump just up the road, we'll use that!
