A pet peeve (or pet hate) is a minor annoyance that can instill great frustration in a very small group of people, yet is experienced by everyone. It also must be insignificant, so people insulting you is not a pet peeve. For example, if you find that elevator doors closing before you can get in annoys you, but does not annoy all the people around you, it is a pet peeve, as it meets all three criteria: insignificant, experienced by all, and only you and a few others are annoyed by it.
