repulsive

This term describes a visceral reaction of disgust, evoking a physical or emotional need to recoil. It is stronger than "unpleasant" or "distasteful," suggesting a level of offense that is nearly unbearable, whether triggered by a foul odor, a gruesome sight, or a morally bankrupt behavior.

In scientific contexts, the word shifts from an emotional judgment to a physical description of force. It describes the mechanical action of pushing objects apart, as seen in electromagnetism, where the term is used neutrally to describe the interaction between similar charges.
