Sagot :
Somos Gordos this means were fat and estamos Gordos means we are fat. Somos is we are and estamos is that we are fat so there's a little difference between them.
Remember that "somos" is used for a permanent situation. So "Somos gordos." does mean "We are fat," but it means that we are fat forever. "Estamos gordos" would mean that we are fat, but only temporarily, so maybe we are fat because we ate a lot at lunch.
