We introduce a concept of squeezing in collective qutrit systems through a geometrical picture connected to the deformation of the isotropic fluctuations of su (3) operators when evaluated in a coherent state. This kind of squeezing can be generated by Hamiltonians nonlinear in the generators of su (3) algebra. A simplest model of such a nonlinear evolution is analyzed in terms of semiclassical evolution of the SU (3) Wigner function.
