to hit a nerve
to say something that makes someone feel upset, angry, or embarrassed because it touches a sensitive topic
What's the situation?
Ever said something totally innocent, only to see someone's face suddenly scrunch up in annoyance? 😬 Or maybe you intentionally brought up a touchy subject to get a reaction? This expression is perfect for those moments when you (or someone else) accidentally or deliberately poke at a sensitive spot in a conversation!
