Disgust is a strong feeling of dislike. Your disgust at pea soup placed in front of you would be obvious if you frown and don't eat a single bite of it.
Disgust is both a noun and a verb. As a noun, it's a reaction to something you think is gross or terrible, like showing your disgust at a movie by getting up and leaving. As a verb, disgust means "to offend," like when your class's bad behavior at the assembly disgusts all the teachers, or "to gross out or revolt." If you pick your nose in public, you will disgust everyone around you.
