running mouth
Won't stop talking
A running mouth won't stop talking, often indiscreetly or excessively.
Someone with a running mouth shares information they shouldn't, gossips freely, or simply talks too much: Her running mouth got her in trouble at work.
The phrase emphasizes lack of control—the mouth runs like a machine that can't be switched off.
