run off at the mouth
Talk without stopping
To run off at the mouth is to talk excessively or indiscreetly, often saying more than one should.
The phrase suggests speech that flows uncontrollably, like water running off: He ran off at the mouth about the surprise party and ruined it.
It implies loose lips rather than thoughtful communication.
