A pet peeve意思

"A pet peeve" is an English idiom that refers to a minor annoyance or irritation that a person finds particularly bothersome, often to an extent that seems disproportionate to the thing itself. The term "pet" in this context means "favorite" or "particular," and "peeve" means "source of irritation." So, a pet peeve is something that a person dislikes more than most people would, and it can be a recurring issue that they often complain about.
