- What’s the most irritating thing my parents say to me?
“Irritating” is an adjective that means causing annoyance, frustration, or mild anger. It describes something or someone that provokes these feelings. For example, a persistent noise like a dripping faucet can be irritating as it constantly disturbs your peace. Or a person who interrupts you all the time while you’re speaking is an irritating person. It implies that the thing or person is getting on your nerves in a relatively minor but still bothersome way.
