Verbal diarrhea is a term used to describe someone who talks excessively without any control. It can be both annoying and exhausting to listen to such a person spouting incessantly. Synonyms for verbal diarrhea include loquaciousness, logorrhea, garrulousness, and wordiness. These words describe the overuse of language in a less-pejorative way than verbal diarrhea. While loquaciousness and garrulousness imply a communicative tendency, logorrhea refers to long-winded and often meaningless dialogue. Wordiness, on the other hand, refers to overusing words to express oneself. In summary, a person with verbal diarrhea could be described as having an overactive mouth, loquacious, logorrhea, garrulous, or verbose.
