A stink refers to a highly offensive smell. Some of its synonyms are stench, foul odor, fetor, malodor and noisomeness.

Halitosis, oral malodor, breath odor, mouth odor, foul breath, fetor oris, fetor ex ore, or most commonly bad breath could be an indication of a more serious health condition. There are a few systemic (non-oral) medical conditions which may cause foul breath odor, but these are extremely infrequent in the general population. Such conditions are: # Fetor hepaticus: an example of a rare type of bad breath caused by chronic liver failure. # Lower respiratory tract infections (Bronchial and lung infections). # Renal infections and renal failure. (Kidney failure) # Carcinoma. # Trimethylaminuria ("fish odor syndrome"). # Diabetes mellitus. # Metabolic dysfunction. Individuals afflicted by the above conditions often show additional, more diagnostically conclusive symptoms than bad breath. People troubled by bad breath should not conclude that they suffer from these conditions or disease.

Another name for this is Halitosis. It is a condition in which a person has bad breath which is foul smelling and often not tolerable by others and it could be so intense in certain situations that a person becomes socially aloof. 20% of the general population are reported to suffer from it
