pet peeve= It's your favorite minor complaint. It's when someone's actions really irritate you and you just can't stand it. It could be irrational, and not even annoy anybody else. It can be different for anyone. For example, I hate it when a person goes to turn while driving, and they don't turn on their indicator. It is something small that bothers you that other people are not bothered by.
