used to express disgust

There are rats here? Ick!

an unpleasantly sticky or congealed substance

she scrubbed the ick off the back of the stove

a sudden feeling of being repelled or disgusted by someone and no longer attracted to them

I spent all day worrying if my chin spot had given her the ick

one of my friends got the ick because the man she was with lost his balance when the train started up
