Turn Someone Off(disgust someone)
How was your date with Marty last night?
Well, it started off OK, but he really turned me off when we went for a snack after the movies.
Did he say or do something to annoy you?
Frankly, he disgusted me when he tried to talk with his mouth full.
I don't blame you. That would have really bothered me too.
disgust = (人をうんざりさせる)
You are disgusting! = あなたって不愉快な人ね！
