Extreme fetid from
one's mouth. Mostly due to the lack of drinking water, eating fruit and vegetable, and poor digestive system.
The smell is characterized by its foulness, significantly different from ordinary smelliness from forgetting to brush
one's teeth in the morning or eating some pungent food (durian).
Shammouth is a result of prolonged unhealthy diet and constipation which renders the smell of
one's shit being raised to the level
one's mouth.
