a vuela lengua - meaning

Question

I can go there and offer remarks a vuela lengua

Answer 1

escribir a vuela pluma means to write without too much thinking, so I think that a vuela lengua means to speak without too much thinking.

But remember,

A veces es mejor pensar lo que se dice que decir lo que se piensa.

Sometimes it`s better to think what you say than to say what you think.
