unsavory

This term describes a visceral sense of repulsion, whether it is triggered by a physical sensation or a moral judgment. When applied to taste or smell, it suggests something foul or off-putting, though it is used less frequently in modern culinary contexts than in descriptions of environmental odors.

In a social or ethical context, the word carries a heavy connotation of suspicion and seediness. It describes people, deals, or reputations that feel "dirty" or illicit, often implying a hidden layer of corruption or impropriety that makes others uncomfortable.
