petulant

Imagine a toddler who throws themselves on the floor because you won't let them have another cookie—that's petulance in action. A petulant person is easily annoyed and expresses their dissatisfaction with childish displays of bad temper, like sulking or whining. It's not just being grumpy; it's a specific kind of irritated behavior that feels immature. You might describe a spoiled prince as petulant if he throws a tantrum when his demands aren't immediately met. While anyone can be irritable sometimes, petulance suggests an unwillingness to handle frustration like an adult.

The word "petulant" describes someone who is childishly sulky or bad-tempered. It goes beyond simple annoyance; it implies a display of irritation that's immature and often unreasonable. Think of a child throwing a fit because they can't have something, but applied to an adult—that's petulance.

You usually use it when the reaction feels out of proportion to the problem. The issue may be small, but the person responds with a sharp, sulky, or childish kind of anger. That is why the word often suggests both annoyance and immaturity at the same time.

You wouldn't typically use "petulant" to describe someone dealing with serious grief or hardship; it suggests a trivial complaint expressed in an overly dramatic way. For example: "The CEO's petulant outburst during the meeting surprised everyone," or "Her petulant refusal to cooperate made the project difficult." It can also be used to describe something exhibiting petulance, like "a petulant tone of voice."

While it's a relatively strong word, it doesn't necessarily imply malice. A petulant person isn't intentionally trying to hurt others; they are simply struggling to manage their emotions in a mature way. So, if someone is acting like a spoiled child despite being an adult, you might describe them as petulant—and perhaps suggest a time-out!
