Morphology
diarrhea + of + the + mouth
The phrase combines 'diarrhea' (an uncontrolled outflow) with 'mouth', so a learner who knows both words can plausibly infer a metaphorical meaning of excessive or uncontrollable talking. Because this is a coarse metaphorical extension rather than a fully literal compositional pattern and relies on pragmatic/conventional usage, it is only partially predictable to learners.
Etymology
Diarrhea of the mouth comes from a strong image: diarrhea is a fast, uncontrolled flow, and the phrase imagines words pouring out of the mouth the same way. So, it is used to describe someone 'talking too much' or who cannot stop speaking.
