Think about a phrase you hate for people to use. It really annoys you, but there are a lot of people who aren’t you that use it.
Write it down. Maybe write down a couple of others.
Got it? Use it/them in a story. Build a character who would use these phrases and invent their story.
You read that correctly. Sometimes you just have to accept that there are phrases that are very common yet very stupid. If you want to write realistic characters, sometimes you have to use them.
It’s hard to write something set in the United States in the 1970s without using the word “groovy,” a word few still use today. Even if you think the word is stupid, it was part of the culture of that setting. That’s just how it was.
If “cray cray” really annoys you, if you can’t stand “YOLO,” find a way to understand the people who use these phrases. Don’t stereotype them in your story. Make a genuine attempt at a character.
You don’t have to like the character. It is okay if you don’t like them. They aren’t your children. You can’t like everyone you meet or create. Just don’t be judgmental. Understand why they are the way they are. Understand why you don’t like them. And accept it.
