An off the cuff maneuver while cycling and leading a few hundred behind you that may result in a bicycle dog pile or a drop from the pack. This can be a sharp left or right turn, an unexpected U-turn, or taking that path less traveled by anyone much less on skinny tires.

A change in route, seemingly unnecessary, but designed to enhance the joy of riding, or an emergency tactic to avoid hazards.
"So, here's this month's route. It's a little on the short side, so be ready for some possible hookie dukes...."
