To stay silent and look upset because you feel angry, hurt, or disappointed. A sulking person often shows their mood without talking about it.

noun

A sulky state or period of silent unhappiness. It is often used in the phrase “in a sulk.”

Adinary Nuance

Sulk is stronger and more childish than just being quiet or unhappy. It suggests someone is showing displeasure on purpose, often by silence, a gloomy face, or stubborn behaviour. Use brood for private, thoughtful unhappiness, and moodily or quietly when there is no clear attitude of protest.
