The phrase "diarrhea of the mouth" is used colloquially to refer to someone who talks too much, often without filtering their words. The spelling of "diarrhea" in this context is based on the English pronunciation of the word, which is /dɪəˈriːə/. The "rrh" in "diarrhea" is based on the Greek root word "rhoia," which means "flow." Therefore, "diarrhea of the mouth" phrasal expression implies that a person's words are flowing excessively without control, much like diarrhea.
Diarrhea of the mouth refers to a colloquial expression used to describe a person who has a tendency to excessively speak or talk in a rapid, uncontrolled, and often thoughtless manner. This phrase is derived from the word "diarrhea," which is a medical condition associated with the frequent passage of loose, watery stool. In this context, it is metaphorically used to liken the uncontrolled flow of words from an individual's mouth to the uncontrolled evacuation of stool in diarrhea.
The term "diarrhea of the mouth" typically implies that a person talks incessantly without much consideration for the appropriateness or relevance of their speech.

This phrase is often used in a critical or negative sense, associated with the perception that the person's excessive talking is burdensome or annoying to others. It may also suggest a lack of substance or meaningful content in their speech, resembling the superficial and uncontrolled nature of diarrhea.
