We examine the conditions under which a large diffusive neutrino flux can destabilize acoustic and magnetoacoustic waves. The instability mechanism is very similar to that responsible for so-called ``photon bubble instabilities'' in radiation magnetohydrodynamics. If such instabilities occur in nature, they may accelerate the escape of neutrinos from the source, and/or introduce anisotropies in the neutrino emission. Such anisotropies may constitute a mechanism for producing neutron star kicks, and be a significant source of gravitational waves.
