"Running on the mouth" is an idiomatic expression often used to describe someone who talks excessively, often without any discernible purpose or regard for others. It refers to a person who speaks endlessly, often rambling or going off on tangents, and frequently monopolizing conversations without allowing others to speak or share their thoughts.
This expression emphasizes the idea that the person's words are flowing without control, much like a faucet or a river running continuously. It implies that the individual lacks self-awareness or consideration for the impact of their excessive talking on others.
The phrase can also suggest that the speaker is engaging in boastful or exaggerated speech, potentially embellishing or stretching the truth in their narratives or claims. It can connote a lack of substance or credibility in the speaker's words, highlighting a tendency to talk without delivering meaningful or accurate information.
Furthermore, "running on the mouth" may imply a lack of listening skills as the person tends to dominate conversations, disregarding the input and perspectives of others. This behavior can result in frustration or annoyance from those who have to endure the non-stop chatter, as it prevents genuine dialogue and exchange of ideas from taking place.
Overall, "running on the mouth" describes an individual who excessively talks without restraint, sometimes exaggerating or lacking substance in their speech, and often hinders effective communication with others.
