When at a four way stop, a biker rides alongside a car whose turn it is, thus bypassing stopping and waiting for their appropriate turn. Cars are unable to latch; latching can only be achieved by bikers and skate boarders
Anytime a biker synchs a move with a car, often using that car as a barrier, in order to bypass traffic laws or travel more expediently.
