"¡Cierra el hocico!" is a bit too long for saying anything else. I'd use it rather to end a discussion... this is what you would normally tell a child who is constantly grumbling back at you as you scold him.

Gracias, Angélica, sí, esas expresiones también se usan en España. (Me recuerda a una canción de Joan Manel Serrat: "¡Niño, deja ya de joder con la pelota! [...] que eso no se dice, que eso no se hace, que eso no se toca..." (Pero eso sería ya otro tema...)

Yet, it seems to me, it is a "reaction" antagonic people, or angry or mad people would say, as "a matter of course".

I would translate this like,
"¡Cállate, aquí soy yo el que habla!"
or
"¡Cállate la boca, aquí el que habla soy yo!" Or other variants could go like
"¡Cierra el pico...!" "¡Que te calles...!"

Is there any other Spanish variants for such an outburst of anger?

Yes when I need to say callate, only I need to say shut up now.
Thank you for the information.
