When someone is said to "run at the mouth," it typically means that they are speaking without restraint or self-control, often in a rambling or unstructured way. Such individuals may vocalize their thoughts, opinions, or ideas without pausing for others to contribute or consider what they have to say. This behavior might be characterized by an excessive flow of words, almost as if the person's mouth is running uncontrollably.
The metaphorical imagery of "running" suggests a lack of control or self-awareness, giving the impression that the person is unable to rein in their speech or filter their thoughts.

Others may perceive this individual as verbose, self-centered, or simply lacking social awareness.
Overall, "run at the mouth" describes someone who engages in prolonged, uninterrupted, and often irrelevant or uninteresting speech. It highlights a lack of self-regulation in their verbal expression, conveying a sense of annoyance or frustration that arises from their excessive babbling.
