Do you know of anywhere else that matezes means from the mouth? Normally it just means to spray or spew, and in the context of rashi it is going on the nechilim, which would mean that it is not talking about the method of leaving the frog at all. Regardless, until there is a mekor that is befaresh not like the gemara, medresh rabba, and zohar, I would assume that that is what rashi means.
