When we are repulsed or disgusted by something, the usual expression is "eww." However, there are plenty of synonyms to describe this feeling. Some of the words we could use include yuck, gross, bleh, yucky, repulsive, nauseating, sickening, offensive, putrid, and revolting. These words can convey the same feeling while also offering variety to our language. We could also use some more humorous terms like yikes, barf, gag, oof, and eww-wee. The choice of word often depends on the level of disgust we are feeling, but each synonym serves its purpose in describing that unpleasant feeling towards something.
