We present a scenario for an anisotropic mass ejection from asymptotic giant branch variables, caused by rotation effects on the inflated atmosphere formed by the stars pulsation. Due to the large radii envolved with the inflated atmosphere, the rotation velocity needed for causing significant anisotropy in the mass loss is dramatically reduced. Possible sources for these rotation velocities are discussed. Such anisotropic mass ejection generates a density contrast in the "slow wind" that can produce the various aspherical morphologies observed in planetary nebulae.
