Plain English Meaning
When you taxi in wind, you steer the control wheel and yoke into or away from the wind so the wind cannot get under a wing and flip or tip the airplane.
Full Definition
Control inputs applied with the ailerons and elevator while taxiing in a crosswind to prevent the wind from lifting a wing or tipping the airplane. The basic rule is 'dive away from a tailwind, climb into a headwind': with a quartering headwind, hold the aileron fully into the wind and keep the elevator neutral; with a , hold the aileron away from the wind ( deflected away from the wind) and the elevator forward (down).
