fed up (with)
Imagine you eat a banana. Then you eat another banana. Then another. After eating 6 bananas, you’d start to dislike bananas (even if you liked them at first). You’d be ‘fed up with’ bananas. ‘I’m fed up’ means ‘I have had too much and now I feel negative’. We use this expression for everything, not just food. It has the same meaning as ‘I’m sick and tired (of)…’. You can be fed up with work, people, traveling, anything at all. People who are fed up sometimes get angry or frustrated, but often they are just really bored.
A: I’m so fed up with the weather. Typhoons, typhoons, typhoons.
B: Last week you were fed up with work. Yesterday you were fed up with your family. Do you think maybe you just have a negative attitude?
A: Whatever. I’m fed up with trying to be positive.
Are you fed up with anything? What?
